\title{Trim Character Strings to Specified Widths}
\description{
  Trim character strings to specified display widths.
}
\usage{
strtrim(x, width)
}
\arguments{
  \item{x}{a character vector, or an object which can be coerced to a
    character vector by \code{\link{as.character}}.}
  \item{width}{Positive integer values: recycled to the length of \code{x}.}
}
\details{
  \sQuote{Width} is interpreted as the display width in a monospaced
  font.  What happens with non-printable characters (such as backspace, tab)
  is implementation-dependent and may depend on the locale (e.g. they
  may be included in the count or they may be omitted).

  Using this function rather than \code{\link{substr}} is important when
  there might be double-width characters in character vectors
}
\value{
  A character vector of the same length and with the same attributes
  as \code{x} (after possible coercion).
  
  Elements of the result will be have the encoding declared as that of
  the current locale (see \code{\link{Encoding}} if the corresponding
  input had a declared encoding and the current locale is either Latin-1
  or UTF-8.
