Inherited from the \href{https://github.com/Rdatatable/data.table/blob/master/R/like.R}{\code{like} function from the \code{data.table} package}, but made it case insensitive at default.

\arguments{
|
||
|
|
\item{x}{a character vector where matches are sought, or an
|
||
|
|
object which can be coerced by \code{as.character} to a character
|
||
|
|
vector. \link{Long vectors} are supported.}
|
||
|
|
|
||
|
|
\item{pattern}{character string containing a \link{regular expression}
|
||
|
|
(or character string for \code{fixed = TRUE}) to be matched
|
||
|
|
in the given character vector. Coerced by
|
||
|
|
\code{\link{as.character}} to a character string if possible. If a
|
||
|
|
character vector of length 2 or more is supplied, the first element
|
||
|
|
is used with a warning. Missing values are allowed except for
|
||
|
|
\code{regexpr} and \code{gregexpr}.}

A \code{logical} vector

\description{
|
||
|
|
Convenience function to compare a vector with a pattern, like \code{\link[base]{grep}}. It always returns a \code{logical} vector and is always case-insensitive.
