Dear Julian
thanks.

Since this has come up here and elsewhere, and since the next Bioc release is coming up, 
let's remind ourselves that we should make development against 3.0.1 Patched (2013-09-03 
r63824) -- "Good Sport".

Martin - should this be noted on 
http://www.bioconductor.org/developers/release-schedule ?
Not sure what relevance this has in practice, but it seems wise to eliminate 
unnecessary variables.


Thanks, the release notes have been updated. A short post to Bioc-devel with some additional pertinent information is forthcoming.

Martin

        Best wishes
                Wolfgang

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
