\arguments{
  \item{packname}{
string naming a package with eset.rda in data folder, defining ExpressionSet instance ex,
and folder parts (from inst in pre-installed image) containing a collection of rda files
holding snpStats \code{\link[snpStats]{SnpMatrix-class}} instances
}
  \item{chrs}{
vector of strings of names of SnpMatrix instances to be included, typically these
are the basenames of files in the \code{parts} folder, and correspond to chromosomes
}
  \item{renameChrs}{
vector of strings of same length of \code{chrs} that will supply names to the
elements of the \code{smList} component of the returned smlSet
}
  \item{probesToKeep}{
vector of strings of probe names to be retained in the returned smlSet
}
  \item{wrapperEndo}{
function receiving and returning an smlSet instance to be invoked prior to
returning the smlSet
}
