\title{resample the columns of a matrix}
\usage{
sample.cols(x, vec = 1:ncol(x), replace = TRUE, incl.first = TRUE)
}
\arguments{
\item{x}{matrix}
\item{vec}{vector, indicates which columns belong together}
\item{replace}{boolean, sampling with or without replacement}
\item{incl.first}{boolean, if \code{TRUE} also the first component is resampled}
}
\value{
Returns a matrix with the same dimensions as \code{x}. The columns are resampled from the original columns. The resampling is done with replacement (\code{replace = TRUE}) or without (\code{replace = FALSE}). Columns which belong together (indicated by vec) are resampled identically, i.e., all values in rows of these are kept together.
