Hi all,

Were there recent changes in GenomicRanges that might cause this?

R> class(sortedBloodCells)
[1] "SummarizedExperiment"
attr(,"package")
[1] "GenomicRanges"

R> showMethods("split")
Function: split (package base)
x="ANY"
x="GRanges"
    (inherited from: x="Vector")
x="RangedData"
x="SummarizedExperiment"
    (inherited from: x="ANY")
x="Vector"

R> split(rowData(sortedBloodCells),
seqnames(rowData(sortedBloodCells)))$chr9
GRanges with 9861 ranges and 0 metadata columns:
## works fine on the rowData GRanges

R> split(sortedBloodCells, seqnames(sortedBloodCells))$chr9
Error in as.vector(x, mode) : invalid 'mode' argument
## used to be delegated via MM's seqinfo fixes, but now... ?

R> packageVersion('GenomicRanges')
[1] '1.11.24'


Thanks,

--t
