\title{Split the data from a DGEList object according to group}

\description{Split the data from a DGEList object according to group}

\usage{ 
splitIntoGroups(object)
}

\arguments{ 
\item{object}{\code{DGEList}, list containing the raw data with elements \code{data} (table of counts), \code{group} (vector indicating group) and \code{lib.size} (vector of library sizes)}
}

\value{ list in which each element is a matrix of count data for an individual group}
