\title{Match fixed characters, not regular expression.}
\usage{
fixed(string)
}
\arguments{
\item{string}{string to match exactly as is}
}
\description{
This function specifies that a pattern is a fixed string,
rather than a regular expression. This can yield
substantial speed ups, if regular expression matching is
not needed.
}
\examples{
pattern <- "a.b"
strings <- c("abb", "a.b")
str_detect(strings, pattern)
str_detect(strings, fixed(pattern))
}
