Summarizes the results of the median comparison function
calcMedians
and the pvalue calculation function
calcPvalues
. Should be used with the matrices originating from
these two functions.
1  calcSummary(medians, pvalues)

medians 
a matrix containing median difference values calculated by
the 
pvalues 
a matrix containing pvalues calculated by the

All genes with a median comparison value >= 0.05 and a pvalue of <= 0.01 are summarized into a data.frame. These genes are assumed to contain a batch effect
A data frame with the columns "gene" containing the gene name, "batch" containing the batch number from which the gene was found, "median" and "pvalue" containing the calculated median difference values and the pvalues, respectively.
