[BioC] dmrFinder error

[genefan [guest]]

dear all, 

I was trying to apply dmrFinder function in bsseq package, but it always gives the following error:

##################################################
dmrs0 <- dmrFinder(BS.cancer.ex.tstat, cutoff = c(-4.6, 4.6))
segmenting
splitting
creating dmr data.frame
Error in ifelse(regions$meanDiff > 0, "hyper", "hypo") : 
  error in evaluating the argument 'test' in selecting a method for function 'ifelse': Error in regions$meanDiff : $ operator is invalid for atomic vectors
##################################################
The code is from http://www.bioconductor.org/packages/2.13/bioc/vignettes/bsseq/inst/doc/bsseq_analysis.R

Thank you for any solution!
best,
Jun
