\begin{Description}\relax
Combine a series of \code{RGList} objects or combine a series of \code{MAList} objects.
\end{Description}
\begin{Usage}
\begin{verbatim}
## S3 method for class 'RGList':
cbind(..., deparse.level=1)
## S3 method for class 'RGList':
rbind(..., deparse.level=1)
\end{verbatim}
\end{Usage}
\begin{Arguments}
\begin{ldescription}
\item[\code{...}] \code{RGList} objects or \code{MAList} objects
\item[\code{deparse.level}] not currently used, see \code{\LinkA{cbind}{cbind}} in the base package
\end{ldescription}
\end{Arguments}
\begin{Details}\relax
\code{cbind} combines data objects assuming the same gene lists but different arrays.
\code{rbind} combines data objects assuming equivalent arrays, i.e., the same RNA targets, but different genes.

For \code{cbind}, the matrices of expression data from the individual objects are cbinded.
The data.frames of target information, if they exist, are rbinded.
The combined data object will preserve any additional components or attributes found in the first object to be combined.
For \code{rbind}, the matrices of expression data are rbinded while the target information, in any, is unchanged.
\end{Details}
\begin{Value}
An \code{\LinkA{RGList}{RGList}} or \code{\LinkA{MAList}{MAList}} object holding data from all the arrays and all genes from the individual objects.
\end{Value}
