[BioC] error when use splicing.index with by.thip=T of exonmap

[Xin Zheng]

Hi all,

I met an error when I use splicing.index with by.chip=T.

> si.em_nv_bychip <- splicing.index(x=x.rma, genes=sig.genes, group="cell_type", members=c("EM", "NV"), by.chip=T)
Error in function (classes, fdef, mtable)  :
  unable to find an inherited method for function "rowttests", for
signature "matrix", "character"

Appreciate any kind help. Thanks.

Xin
