|---|---|
| Description: | A tool for fast, efficient bitwise operations along the elements within a vector. Provides such functionality for AND, OR and XOR, as well as infix operators for all of the binary bitwise operations. |

Basic infix wrapper around the base::bitw_OP_ operations.

a, b
|
Integer vectors. Numerics are coerced to integers. |
n |
Non-negative integer vector of values up to 31. |
An integer vector of length of the longer of the arguments, or zero if one of the arguments is zero-length. NA input makes NA output.
%|%: A vector of pairwise ORed values.
%&%: A vector of pairwise ANDed values.
%^%: A vector of pairwise XORed values.
%<<%: A vector of the values on the LHS pairwise left-shifted by the RHS value.
%>>%: A vector of the values on the LHS pairwise right-shifted by the RHS value.

Functions to apply the same bitwise operation sequentially down a vector of integers. A fast way to AND or OR everything together when a single value is required.

vec |
A vector of integers. Numeric vectors will be coerced to int. |
A single integer, the result of applying the operation in question along the vector. Input that cannot be coerced to int returns NA. An empty vector returns 0.
bit_vector_AND: A single integer, the result of ANDing each entry in the input vector together.
bit_vector_OR: A single integer, the result of ORing each entry in the input vector together.
bit_vector_XOR: A single integer, the result of XORing each entry in the input vector together.
