\description{
  \code{processData} is used to estimate data processing parameters and
  \code{applyProcessing} takes the results  and applies them to data objects
}
\usage{
processData(x, center = TRUE, scale = TRUE, na.remove = TRUE)
applyProcessing(x, object)
}
\arguments{
  \item{x}{A matrix or data frame with variables in rows and samples in columns}  
  \item{center}{A boolean to center the data.}
  \item{scale}{A boolean to scale the data.}
  \item{na.remove}{Should \code{NA} values be removed?}
  \item{object}{the results from a previous call to \link{processData}.}
}

\value{
\code{x}, after it has been processed.
