\title{ Get control probe information }
\description{
  Get control probe information from Bead Studio output or a LumiBatch object.
}
\usage{
getControlData(x, type = c('data.frame', 'LumiBatch'), ...)
}
%- maybe also 'usage' for other objects documented here.
\arguments{
  \item{x}{ the control data can be a LumiBatch object or the Control Probe Profile file outputted by BeadStudio }
  \item{type}{ determine the return data type }
  \item{\dots}{ other parameters used by \code{\link{lumiR}} function }
}
\value{
   By default, it returns a data.frame with first two columns as "controlType" and "ProbeID". The rest columns are the expression amplitudes for individual samples. When type is 'LumiBatch', it returns a LumiBatch object, which basically is the return of lumiR without combining duplicated TargetIDs. As the return is a LumiBatch object, it includes more information, like probe number, detection p-value and standard error of the measurement.
