I am having some trouble with the dmrFinder function that is part of bsseq. The code that I running

                                  estimate.var = "group2",
                                  local.correct = TRUE,

>dmrs0 = dmrFinder(rrbs.fitted.tstat)

receives an error:

Error in quantile.default(x, ...) : 
  missing values and NaN's not allowed if 'na.rm' is FALSE

I take it that the reason for this error is because there are missing values in the rrbs.fitted.tstat object.

Is there a way to disregard these missing values when considering the rrbs.fitted.tstat class? I've tried na.omit(rrbs.fitted.tstat) but that did not work.
