A vector of geneNames
Summarizes probe-level data to gene-level data, using the mean of the probes, according to the probe:gene mapping in the
$keys item in the dataset object. This is done only for the genes in the filter object.
Returns a data frame with expression levels of only the genes of interest, for each sample in the dataset. Mostly used internally, but has been exposed to the user to allow advanced functionality on external datasets if desired.
