RPA.pointestimate is used to calculate probe reliability and
differential expression estimates: 'rpa.results <-
RPA.pointestimate(affybatch)'. The other functions are provided for
users who wish to investigate the details of the algorithm more
closely.

\examples{

  ## Not run:

  ## Load example data set (Dilution affybatch).
  ## This is a toy example with a small example dataset
  ## for probe reliability analysis (4 arrays).
  ## For practical applications, a larger sample size is
  ## recommended.

  #require(affy)
  #require(affydata)
  #data(Dilution)

  ## Compute RPA for whole data set
  ## ... slow, not executed here
  #rpa.results <- RPA.pointestimate(Dilution)
