\alias{str_sub_replace}
\title{Replace substrings in a character vector.
\code{str_sub<-} will recycle all arguments to be the same length as the
longest argument.}
\usage{
str_sub(string, start = 1L, end = -1L) <- value
}
\arguments{
\item{string}{input character vector.}
\item{start}{integer vector giving position of first
charater in substring, defaults to first character. If
negative, counts backwards from last character.}
\item{end}{integer vector giving position of last
character in substring, defaults to last character. If
negative, counts backwards from last character.}
\item{value}{replacement string}
}
\value{
character vector of substring from \code{start} to
\code{end} (inclusive). Will be length of longest input
argument.
}
\description{
Replace substrings in a character vector.
\code{str_sub<-} will recycle all arguments to be the
same length as the longest argument.
