I have a gene expression data `AllExp` and a data.frame `info` with sample name of `AllExp` as row names and first column in it specifies groups that each sample belongs to.
I am trying to perform a a gene set enrichment analysis using GSA package. but I get following error
`Error in cut.default(sd, br, labels = F) : invalid number of intervals`
GS <- Sys.glob("E:/gmts/h.all.v6.1.symbols.gmt") GS <- GSA.read.gmt(GS) GSA(AllExp, y=factor(info[,1]), genesets=GS$genesets, genenames = row.names(AllExp),method="maxmean", resp.type="Multiclass", minsize=10)
what is wrong with my code?
