Insert Arrow emojis

Description

Insert Arrow emojis

Usage

arrow(direction)

Arguments

direction

Character denoting the direction of the arrow. Should be one of “up”, “up-right”, “right”, “down-right”, “down”, “down-left”, “left”, “up-left”, “up-down”, or “left-right”.

Details

This function is vectorized. Wrong input of direction will result in NAs.

#@return Character vector of emojis.

Examples

arrow("up-down")

arrow(c("up", "up", "down", "down", "left", "right", "left", "right"))

emoji version of time

Description

emoji version of time

Usage

clock(time)

Arguments

time

a POSIXct object

Details

This function is vectorized.

Value

Character vector of emojis showing the closest time.

Examples

times <- as.POSIXct("2021-09-17 14:33:21 PDT") + seq(1:30) * 3500
clock(times)

Find a single emoji

Description

This function starts by looking for exact matches in emoji_name. If none is found in emoji_name then it looks in emoji_keyword. emoji_keyword can produce more then 1 matches, which will lead to one being returned at random.

Usage

emoji(keyword)

Arguments

keyword

Character, either name or keyword. If more than one emoji has the specified keyword, will pick one at random.

Details

This function isn't vectorized and will thus only work with 1 keyword at a time.

Examples

emoji("smile")
emoji("taco")

set.seed(1234)
replicate(24, emoji("clock"))
replicate(10, emoji("flag"))

Count the number of emojis in a string

Description

Vectorised over string

Usage

emoji_count(string)

Arguments

string

Input vector

Value

An integer vector

See Also

stringr::str_count()

Examples

string <- paste(c(letters[1:4], emoji_name[1:6]), collapse = " ")

emoji_count(string)

emoji_count(emoji_name[1:6])

Detect the presence or absence of emojis in a string

Description

Vectorised over string

Usage

emoji_detect(string, negate = FALSE)

Arguments

string

Input vector. Either a character vector, or something coercible to one.
negate

If TRUE, inverts the resulting boolean vector.

Value

A logical vector

See Also

stringr::str_detect()

Examples

string <- c(letters[1:4], emoji_name[1:6])
emoji_detect(string)

Extract emojis from a string

Description

vectorised over string

Usage

emoji_extract(string)

emoji_extract_all(string, simplify = FALSE)

Arguments

string

Input vector.
simplify

see stringr::str_extract_all()

Value

A character vector

See Also

stringr::str_extract() and stringr::str_extract_all()

Examples

chars <- c(letters[1:4], emoji_name[1:6])

set.seed(1234)

strings <- lapply(1:10, function(x) paste(sample(chars, x), collapse = ""))

extracts <- emoji_extract(strings)

all_extracts <- emoji_extract_all(strings)

List all emoji with a given keyword

Description

This function will look in emoji_keyword to report back the given emojis.

Usage

emoji_find(keyword)

Arguments

keyword

Character, Emoji keyword.

Examples

emoji_find("happy")
emoji_find("cat")
emoji_find("family")

Turn emojis into qualified emojis

Description

Some emojis can be written in multiple different ways either as fully-qualified, minimally-qualified, or unqualified. emoji_fix() will take any emoji and return the fully-qualified version of that emoji.

Usage

emoji_fix(x)

Arguments

x

Characters, vector of emojis.

Details

This function is vectorized.

Value

vector of fully-qualified emojis

Examples

unqualified_ind <- which(emojis$qualified == "unqualified")[1:10]
unqualified <- emojis$emoji[unqualified_ind]

unqualified
emoji_fix(unqualified)

Glue Interpolation for Emojis

Description

Combine the power of glue::glue and emoji().

Usage

emoji_glue(..., .envir = parent.frame())

Arguments

...

[expressions]
Unnamed arguments are taken to be expression string(s) to format. Multiple inputs are concatenated together before formatting. Named arguments are taken to be temporary variables available for substitution.

For glue_data(), elements in ... override the values in .x.
.envir

[environment: parent.frame()]
Environment to evaluate each expression in. Expressions are evaluated from left to right. If .x is an environment, the expressions are evaluated in that environment and .envir is ignored. If NULL is passed, it is equivalent to emptyenv().

Details

emoji_glue() behaves in much the same way a lot of messaging apps work. Anything inside a pair of : will be interpolated into an emoji. You can think of emoji_glue() as being a shorthand for glue("I love {emoji('taco')}s").

Block ending with * will be collapsed.

Value

a glue::glue() string.

Examples

emoji_glue("I love :taco:s")

emoji_glue("one :heart:")
emoji_glue("many :heart*:")

Emoji Keywords

Description

This list contains information about which emojis are contained in which keywords.

Usage

emoji_keyword

Format

named list of characters with 7665 elements
