\title{Write data to a file}
\usage{
write(x, file="data",
        ncolumns=if(is.character(x)) 1 else 5,
        append=FALSE)
}
\alias{write}
\arguments{
\item{x}{the data to be written out.}
\item{file}{the name of the file (quoted) to write to.}
\item{ncolumns}{the number of columns to write the data in.}
\item{append}{if \code{TRUE} the data \code{x} is appended to file \code{file}.}
}
\description{
The data (usually a matrix) \code{x} are written to file \code{file}.
If \code{x} is a two dimensional matrix you need to transpose it to get the
columns in \code{file} the same as those in the internal representation.
}
\seealso{
\code{\link{scan}} for reading data.
}
\examples{
# create a 2 by 5 matrix
x <- matrix(1:10,ncol=5)

# the file data contains x, two rows, five cols
# 1 3 5 6 9 will form the first row
write(t(x))

# the file data now contains the data in x,
# two rows, five cols but the first row is 1 2 3 4 5
write(x)
