[Bioc-devel] IRanges: 'extractROWS' fails for 'RangedData'

[Julian Gehring]

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
