hi,

I'm using the estimate.mean.fraglen function to estimate the average
fragment length in a ChIPseq dataset.
when I use the method="correlation" setting I get however the following
error message:

> Test <- estimate.mean.fraglen( AlignedReads[[2]], method="correlation" )
Error in if (from > from0 || to < to0) stop("[from, to] smaller than support
not implemented yet (but easy to add)") :
  missing value where TRUE/FALSE needed
Error in unlist(lapply(splitData, function(y) { :
  error in evaluating the argument 'x' in selecting a method for function
'unlist'

is there any solution to this problem?

bests, jo
