Hi,
calling 'head' or 'tail' on a 'RangedData' objects fail with the lastest
builds (R: 2013-09-14 r63932, IRanges: 1.19.35). The cause seems to be
that there is no 'extractROWS' method that can be found for the
signature 'RangedData'. As an example, see:
'''
library(IRanges)
## generate the data
ranges <- IRanges(c(1,2,3),c(4,5,6))
rd = RangedData(ranges)
## this fails
head(rd)
'''
The last command returns: Error in (function (classes, fdef, mtable) :
unable to find an inherited method for function ‘extractROWS’ for
signature ‘"RangedData"’
Best wishes
Julian
