\title{Class \code{"oligoPLM"}}
\description{
  A class to represent Probe Level Models.
}
\section{Objects from the Class}{
  Objects can be created by calls of the form
  \code{fitProbeLevelModel(FeatureSetObject)}, where
  \code{FeatureSetObject} is an object obtained through
  \code{read.celfiles} or \code{read.xysfiles}, representing intensities
  observed for different probes (which are grouped in probesets or
  meta-probesets) across distinct samples.
