\title{Count the Number of Characters}
\usage{nchar(x)}
\alias{nchar}
\description{
  \code{nchar} takes a character vector as an argument and
  returns a vector whose elements contain the number of characters in
  the corresponding element of \code{x}.
}
\arguments{
  \item{x}{character vector, or a vector to be coerced to a character
    vector.} 
}
\details{
  The internal equivalent of \code{\link{as.character}} is performed on
  \code{x}. If you want to operate
  on non-vector objects passing them through \code{\link{deparse}} first
  will be required.
}
\value{
  The number of characters as the string will be printed (integer
  \code{2} for a missing string).
