msva: Surrogate Variable Analysis

#' sva: a package for removing artifacts from microarray and sequencing data 
#'
#' sva has functionality to estimate and remove artifacts from high dimensional data
#' the \code{\link{sva}} function can be used to estimate artifacts from microarray data
#' the \code{\link{svaseq}} function can be used to estimate artifacts from count-based
#' RNA-sequencing (and other sequencing) data. The \code{\link{ComBat}} function can be
#' used to remove known batch effecs from microarray data. The \code{\link{fsva}} function
#' can be used to remove batch effects for prediction problems. 
#' 
#' 
#' A vignette is available by typing \code{browseVignettes("sva")} in the R prompt.
