When running
champ.DMP(), if there is only one differentially expressed probe, the following fails:because
com.idxhas length 1, andbeta[com.idx,which(pheno==Com 8000 pare[[i]][1])]instead of a matrix becomes a vector, over which cannot be computed row names. By addingdrop=FALSE, we can make it return a matrix with one row, and the operation works.In the patch I've also removing the use of
which()as it seems unnecessary. The only case where it would make a difference is ifphenoorComparecontain NAs, but I don't know if that is actually possible. In case, I can put the 'which()' back.
