\usage{
read.450k(basenames, extended = FALSE, verbose = FALSE)
}
\arguments{
  \item{basenames}{The basenames or filenames of the IDAT files.  By
    basenames we mean the filename without the ending \code{_Grn.idat}
    or \code{_Red.idat} (such that each sample occur once).  By
    filenames we mean filenames including \code{_Grn.idat}
    or \code{_Red.idat} (but only one of the colors)}
  \item{extended}{Should a \code{RGChannelSet} or a
    \code{RGChannelSetExtended} be returned. }
  \item{verbose}{Should the function be verbose?}
}
\value{
  An object of class \code{RGChannelSet} or
  \code{RGChannelSetExtended}.
