Check ISO country code

Description

Check whether an ISO country code is valid.

Usage

check_cc(country)
check_cc(country)

Arguments

country

A character vector of ISO country codes.

Value

A logical vector flagging which elements are valid codes.

Examples

check_cc(c("AU", "US", "CN", "WRONG", NA))
check_cc(c("AU", "US", "CN", "WRONG", NA))

Get an example phone number

Description

Produces example phone numbers for the given region, type and valid combinations. Input vectors are recycled as necessary if a vector of length 1 is provided.

Usage

get_example(region, type = NULL, valid = TRUE)
get_example(region, type = NULL, valid = TRUE)

Arguments

`region`	A character vector of ISO country codes.
`type`	A character vector of phone number types for each region. If `NULL` (default), returns an example "FIXED_LINE" number. Returns an empty phone number if `type` is not valid for the provided `region`.
`valid`	A logical vector. For each `FALSE` entry, `get_example` returns an example invalid number, and `type` is ignored.

Value

A phone vector.

libphonenumber reference

get_example(): PhoneNumberUtil.getExampleNumberForType(); PhoneNumberUtil.getExampleNumber() if type is NULL or NA; PhoneNumberUtil.getInvalidExampleNumber() if valid is FALSE.

Examples

# Get a basic example number

# Get an example mobile number
get_example("AU", type = "MOBILE")

# Example phone number for an invalid type
get_example("AU", type = "VOICEMAIL")

Phone number equality checks

Description

Check if two vectors contain matching phone numbers. See Details section for a full list of match types. is_match() with default arguments is used to implement == and != for phone vectors.

is_match() accepts phone or atomic vectors. Atomic vectors are converted to character for comparison. Note that although they can contain formatting character vectors are not parsed with a default region, so they will only ever be an "EXACT_MATCH" if a country calling code is specified with + at the start. See Examples.

Usage

is_match(e1, e2, detailed = FALSE, strict = TRUE, not_number_na = TRUE)
is_match(e1, e2, detailed = FALSE, strict = TRUE, not_number_na = TRUE)

Arguments

`e1`	A phone or character vector.
`e2`	A phone or character vector.
`detailed`	If `FALSE`, `is_match()` returns a logical vector. If `TRUE`, it returns a character vector with the match type. See Details section for possible return values.
`strict`	If `TRUE`, only `"EXACT_MATCH"` is treated as a match. If `FALSE`, `"EXACT_MATCH"`, `"NSN_MATCH"` and `"SHORT_NSN_MATCH"` are all considered a match. Ignored if `detailed = TRUE`.
`not_number_na`	If `TRUE`, `"NOT_A_NUMBER"` is converted to `NA`.

Details

Possible return values for is_match(x, detailed = TRUE):

"EXACT_MATCH": The country_code, NSN, presence of a leading zero for Italian numbers and any extension present are the same.
"NSN_MATCH": Either or both values has no region specified, and the NSNs and extensions are the same.
"SHORT_NSN_MATCH": Either or both values has no region specified, or the region specified is the same, and one NSN could be a shorter version of the other number. This includes the case where one has an extension specified, and the other does not.
"NOT_A_NUMBER": One of the input phone numbers failed to parse.
"NO_MATCH": All others.

For example, the numbers ⁠+1 345 657 1234⁠ and ⁠657 1234⁠ are a "SHORT_NSN_MATCH". The numbers ⁠+1 345 657 1234⁠ and ⁠345 657⁠ are a "NO_MATCH".

Value

A logical or character vector.

Phone number parsing and formatting

Description

A phone vector stores phone numbers parsed with libphonenumber for formatting and further processing.

Usage

phone(
  x = character(),
  region = character(),
  show_progress = getOption("dialr.show_progress")
)

phone_reparse(x)

is.phone(x)

## S3 method for class 'phone'
print(x, n = 10, ...)

## S3 method for class 'phone'
format(
  x,
  format = c("E164", "NATIONAL", "INTERNATIONAL", "RFC3966"),
  home = NULL,
  clean = TRUE,
  strict = FALSE,
  ...
)

## S3 method for class 'phone'
as.character(x, raw = TRUE, ...)
phone(
  x = character(),
  region = character(),
  show_progress = getOption("dialr.show_progress")
)

phone_reparse(x)

is.phone(x)

## S3 method for class 'phone'
print(x, n = 10, ...)

## S3 method for class 'phone'
format(
  x,
  format = c("E164", "NATIONAL", "INTERNATIONAL", "RFC3966"),
  home = NULL,
  clean = TRUE,
  strict = FALSE,
  ...
)

## S3 method for class 'phone'
as.character(x, raw = TRUE, ...)

Arguments

`x`	A character vector of phone numbers.
`region`	A character vector of ISO country codes with the default region for each phone number in `x`. A `region` vector of length 1 will be recycled to the length of `x`. If `NA` or `""`, numbers written in international format (with a leading `+`) will be parsed without a default region.
`show_progress`	Should a progress bar be displayed? Defaults to the option `dialr.show_progress`.
`n`	Number of elements to print.
`...`	Additional arguments for specific methods.
`format`	Phone number format to use from one of four standards: `"E164"`: general format for international telephone numbers from ITU-T Recommendation E.164 `"NATIONAL"`: national notation from ITU-T Recommendation E.123 `"INTERNATIONAL"`: international notation from ITU-T Recommendation E.123 `"RFC3966"`: "tel" URI syntax from the IETF tel URI for Telephone Numbers See notes from the libphonenumber javadocs for more details. `format` defaults to `"E164"`. The default can be set in option `dialr.format`.
`home`	ISO country code for home region. If provided, numbers will be formatted for dialing from the home region.
`clean`	Should non-numeric characters be removed? If `TRUE`, keeps numbers and leading `"+"`.
`strict`	Should invalid phone numbers be removed? If `TRUE`, invalid phone numbers are replaced with `NA`.
`raw`	If `TRUE`, the raw phone number is returned. Otherwise elements are cleaned with `format()`.

Details

libphonenumber defines the PhoneNumberUtil class, with a set of functions for extracting information from and performing processing on a parsed Phonenumber object. A text phone number must be parsed before any other operations (e.g. checking phone number validity, formatting) can be performed. When parsing a phone number a "default region" is required to determine the processing context for non-international numbers.

A phone vector stores the raw phone number, the default region and a java Phonenumber object for each element. The java object is cached so should persist between R sessions. In case of issues, use phone_reparse() to recreate the phone vector from the original phone number and region.

Phone number parsing functions display a progress bar in interactive sessions by default. This can be disabled globally by setting option dialr.show_progress to FALSE, or locally using the show_progress function argument.

libphonenumber reference

phone(): Phone numbers are parsed using PhoneNumberUtil.parseAndKeepRawInput(). A phone vector stores the returned Phonenumber.PhoneNumber object alongside the original raw text and default region for later reference.

format(): PhoneNumberUtil.format() by default, or PhoneNumberUtil.formatOutOfCountryCallingNumber() if home is provided.

Examples

  # Create a phone vector
  x <- phone(c(0, 0123, "0412 345 678", "61412987654", "03 9123 4567", "+12015550123"), "AU")
  
  is.phone(x)
  print(x)
  as.character(x)
  format(x)
  format(x, home = "AU")
  
  # Parse international number with no default region
  phone("+61412345678", NA)
  
  # Will fail to parse if number is not in international format
  phone("0412345678", NA)
  
  # A combination can be used
  phone(c("+61412345678", "0412345678"), c(NA, "AU"))
# Create a phone vector
  x <- phone(c(0, 0123, "0412 345 678", "61412987654", "03 9123 4567", "+12015550123"), "AU")
  
  is.phone(x)
  print(x)
  as.character(x)
  format(x)
  format(x, home = "AU")
  
  # Parse international number with no default region
  phone("+61412345678", NA)
  
  # Will fail to parse if number is not in international format
  phone("0412345678", NA)
  
  # A combination can be used
  phone(c("+61412345678", "0412345678"), c(NA, "AU"))

Phone number region

Description

In libphonenumber a phone number region is represented by a 2 digit ISO country code. get_region(x) returns the 2-digit ISO country code for each element of a phone vector.

Use get_supported_regions() to see a full list of supported regions.

Region can also be retrieved from an international calling code. get_region_for_calling_code(x) returns the main region for each provided calling code. Since multiple regions can share a single calling code, get_regions_for_calling_code(x) returns a list of character vectors of regions for each.

Usage

get_region(x)

get_supported_regions()

get_region_for_calling_code(x)

get_regions_for_calling_code(x)
get_region(x)

get_supported_regions()

get_region_for_calling_code(x)

get_regions_for_calling_code(x)

Arguments

`x`	A phone vector, or a vector of calling codes.

Value

A character vector of country codes.

get_regions_for_calling_code() returns a list of character vectors for each provided calling code.

Phone number type

Description

In addition to validity, libphonenumber can identify phone number type - it is able to distinguish Fixed-line, Mobile, Toll-free, Premium Rate, Shared Cost, VoIP, Personal Numbers, UAN, Pager, and Voicemail (whenever feasible).

get_type(x) returns the phone number type for each element of a phone vector.

Valid phone number types differ by region. get_types_for_region(x) returns a list of character vectors of valid types for each provided ISO country code. Use get_supported_types() to see a full list of supported types.

Usage

get_type(x, strict = FALSE)

get_supported_types()

get_type(x, strict = FALSE)

get_supported_types()

get_types_for_region(x)

Arguments

`x`	A phone vector, or a character vector of ISO country codes.
`strict`	If `TRUE`, invalid phone numbers return `NA`.

Value

A character vector of phone types.

get_types_for_region() returns a list of character vectors for each provided country code.

Phone number validity checks

Description

For each element of x:

is_parsed(x): Was this successfully parsed?
is_valid(x): Is this a valid phone number?
is_possible(x): Is this a possible phone number? Return type depends on detailed.

Usage

is_parsed(x)

is_valid(x)

is_possible(x, detailed = FALSE, type = NULL)
is_parsed(x)

is_valid(x)

is_possible(x, detailed = FALSE, type = NULL)

Arguments

`x`	A phone vector.
`detailed`	If `FALSE`, `is_possible` returns a logical vector. If `TRUE`, it returns a character vector with `"IS_POSSIBLE"` or the reason for failure. See Details section for possible return values.
`type`	If provided, checks if `x` is possible for the given phone number type.

Details

Possible return values for is_possible(x, detailed = TRUE):

"INVALID_COUNTRY_CODE": The number has an invalid country calling code.
"INVALID_LENGTH": The number is longer than the shortest valid numbers for this region, shorter than the longest valid numbers for this region, and does not itself have a number length that matches valid numbers for this region.
"IS_POSSIBLE": The number length matches that of valid numbers for this region.
"IS_POSSIBLE_LOCAL_ONLY": The number length matches that of local numbers for this region only (i.e. numbers that may be able to be dialled within an area, but do not have all the information to be dialled from anywhere inside or outside the country).
"TOO_LONG": The number is longer than all valid numbers for this region.
"TOO_SHORT": The number is shorter than all valid numbers for this region.

Phone number carrier information

Description

Returns a carrier name for each phone number, in the language provided in locale.

Usage

get_carrier(

  strict = FALSE,
  safe = FALSE,
  locale = getOption("dialr.locale")
)
get_carrier(
  x,
  strict = FALSE,
  safe = FALSE,
  locale = getOption("dialr.locale")
)

Arguments

`x`	A phone vector.
`strict`	Should invalid phone numbers be removed? If `TRUE`, invalid phone numbers are replaced with `NA`.
`safe`	If `TRUE`, gets the name of the carrier for a given phone number only when it is 'safe' to display to users. A carrier name is considered safe if the number is valid and for a region that doesn't support mobile number portability. All other phone numbers return `""`.
`locale`	The Java locale used to retrieve localised results. The default is set in option `dialr.locale`.

Details

The carrier name is the one the number was originally allocated to, however if the country supports mobile number portability the number might not belong to the returned carrier anymore. If no mapping is found "" is returned.

Value

A carrier name for each phone number for the given locale, or "" if the number is invalid.

libphonenumber reference

get_geocode(): PhoneNumberToCarrierMapper.getNameForValidNumber() by default, or PhoneNumberToCarrierMapper.getSafeDisplayName() if safe = TRUE.

Usage

get_cc(country)
get_cc(country)

Arguments

country

A character vector of country names.

Value

A vector of ISO country codes (NA where not found).

Examples

get_cc(c("Australia", "China", "United states"))
get_cc("Australia")
get_cc(c("Australia", "China", "United states"))

Phone number geographical information

Description

Returns a text description for each phone number, in the language provided in locale.

Usage

get_geocode(x, home = NULL, strict = FALSE, locale = getOption("dialr.locale"))
get_geocode(x, home = NULL, strict = FALSE, locale = getOption("dialr.locale"))

Arguments

`x`	A phone vector.
`home`	ISO country code for home region. See Details.
`strict`	Should invalid phone numbers be removed? If `TRUE`, invalid phone numbers are replaced with `NA`.
`locale`	The Java locale used to retrieve localised results. The default is set in option `dialr.locale`.

Details

The description might consist of the name of the country where the phone number is from, or the name of the geographical area the phone number is from if more detailed information is available.

If a phone number is from the region specified in home, only a lower-level description will be returned, if one exists. Otherwise, the phone number's region will be returned, with optionally some more detailed information.

For example, for a user from the region "US" (United States), we would show "Mountain View, CA" for a particular number, omitting the United States from the description. For a user from the United Kingdom (region "GB"), for the same number we may show "Mountain View, CA, United States" or even just "United States".

Value

A text description for each phone number for the given locale, or "" if the number is invalid or could belong to multiple countries.
