[BioC] MTP error

[Boel Brynedal]

Dear List,

I am trying to use the MTP function in the multtest package. I get the
following error:

> mtp<-MTP(X=exprs(eS), Y=groupMO, test="t.twosamp.unequalvar",
robust=FALSE, typeone="fdr", method="sd.minP")
running bootstrap...
iteration = 100 200 300 400 500 600 700 800 900 1000

Error in pmin(na.rm, ...) : cannot mix 0-length vectors with others

Can anyone see what I am doing wrong? Any tips will be appreciated.
