\keyword{manip}{rmaplus}
\begin{Description}\relax
Calculate the RMA+ intensities using pre-stored reference quantiles and probe
effects. The reference quantiles and the probe effects are the estimated 
parameter values from RMAing a set of microarrays (e.g. a reference set).
\end{Description}
\begin{Usage}
\begin{verbatim}
rmaplus(Future, rmapara, r.q, p.e, bg = TRUE)
\end{verbatim}
\end{Usage}
\begin{Arguments}
\begin{ldescription}
\item[\code{Future}] An \code{affybatch} object of the microarrays to be 
pre-processed using the RMA+ methods.
\item[\code{rmapara}] Output of \code{rma.para} function that the contain reference 
quantiles and the reference probe effects.
\item[\code{r.q}] The pre-stored vector of the quantiles that the 
probe intensity data of a microarray should be normalized to.
\item[\code{p.e}] A pre-stored list of probe effects. It is a probe.coefs object of 
PLMset class in \code{affyPLM} package.
\item[\code{bg}] A logical flag. If \code{True}(by default), background correct 
\code{Train} using default \code{bg.correct.rma}. 
\end{ldescription}
\end{Arguments}
\begin{Value}
The RMA+ intensities of \code{Future}.

\begin{Examples}
\begin{ExampleCode}
## Use affybatch.example in affy package
data(affybatch.example)

##Calculate RMA intensities using the rma function.
Ex0<-exprs(rma(affybatch.example))

## Background correct, estimate the probe effects, and calculate the 
## RMA intensities using rma.para function.
Para<-rma.para(affybatch.example,bg=TRUE,exp=TRUE)
Ex1<-Para[[3]]
 
## Calculate the RMA+ intensity using rmaplus function. 
Ex2<-rmaplus(affybatch.example, rmapara=Para, bg = TRUE)
