capture |
A logical value indicating whether or not the result should be captured. See note. |
x |
A character vector. |
y |
A character vector. |
A character vector representing part or all of a regular expression.
or takes multiple character vector inputs and returns a
character vector of the inputs separated by pipes. %|% is an operator
interface to this function. or1 takes a single character vector and
returns a string collapsed by pipes.
# or takes an arbitrary number of arguments and groups them without capture
# Notice the recycling of inputs
or(letters, month.abb, "foo")
# or1 takes a single character vector
or1(c(letters, month.abb, "foo")) # Not the same as before!
# Capture the group
or1(letters, capture = TRUE)
# Don't create a group
or1(letters, capture = NA)
# The pipe operator doesn't group
letters %|% month.abb %|% "foo"
# Usage
(rx <- or("dog", "cat", "hippopotamus"))
