[BioC] GO terms

[Heidi Dvinge]

Hello Adrian,

could you perhaps provide your sessionInfo? When I use the examples
provide on probeSetSummary in GOstats to create an object called ps, I can
then say:

> ps[1]
$`GO:0043412`
    EntrezID ProbeSetID selected
1      10114     102_at        1
2      10114   41501_at        0
3      10114   41502_at        0
4      10152  1040_s_at        1
5      10152   135_g_at        0
...
