I am trying to figure out what information is provided by the gage() function. once the gage() function is produced, it provides three values (greater, less, stats). Under stats, it has stat.mean and exp1. I can't find any information on exp1 in the bioconductor manual I found here (https://bioconductor.org/packages/devel/bioc/manuals/gage/man/gage.pdf). Would anyone know what it means?

All the columns except for 'stat.mean' come from the input data. As an example, using the help page for gage:

 data(gse16873)
 cn=colnames(gse16873)
 hn=grep('HN',cn, ignore.case =TRUE)
 dcis=grep('DCIS',cn, ignore.case =TRUE)
 data(kegg.gs)
 data(go.gs)
#go.gs with the first 1000 entries as a fast example.
  gse16873.go.p <- gage(gse16873, gsets = go.gs, 
         ref = hn, samp = dcis)
> head(gse16873)
