\title{Subset samples by sampleData expression}
\usage{
  subset_samples(physeq, ...)
}
\arguments{
  \item{physeq}{A \code{\link{sampleData-class}}, or a
  \code{\link{phyloseq-class}} object with a
  \code{sampleData}. If the \code{sampleData} slot is
  missing in \code{physeq}, then \code{physeq} will be
  returned as-is, and a warning will be printed to screen.}

  \item{...}{The subsetting expression that should be
  applied to the \code{sampleData}. This is passed on to
  \code{\link{subset}}, see its documentation for more
  details.}
}
\value{
  A subsetted object with the same class as \code{physeq}.
}
\description{
  This is a convenience wrapper around the
  \code{\link{subset}} function. It is intended to allow
  subsetting complex experimental objects with one function
  call. The subsetting will be based on an expression
  related to the columns and values within the sampleData.
