\name{str_split}
\alias{str_split}
\title{Split up a string into a variable number of pieces.}
\usage{
str_split(string, pattern, n = Inf)
}
\arguments{
\item{string}{input character vector}
\item{pattern}{pattern to split up by, as defined by a
POSIX regular expression. See the ``Extended Regular
Expressions'' section of \code{\link{regex}} for details.
If \code{NA}, returns original string. If \code{""}
splits into individual characters.}
\item{n}{maximum number of pieces to return. Default
(Inf) uses all possible split positions.}
}
\value{
a list of character vectors.
}
\description{
Vectorised over \code{string}. \code{pattern} should be
a single pattern, i.e. a character vector of length one.
}
\examples{
fruits <- c(
"apples and oranges and pears and bananas",
"pineapples and mangos and guavas"
)
str_split(fruits, " and ")
# Specify n to restrict the number of possible matches
str_split(fruits, " and ", n = 3)
str_split(fruits, " and ", n = 2)
# If n greater than number of pieces, no padding occurs
str_split(fruits, " and ", n = 5)
}
