[BioC] makeGOGraph error

[Bosotti, Roberta [Nervianoms]]

Hi list,

just drop a line to update you on the issue I had with makeGOGraph.
The problem was due to the old version of GOstats I was using (1.1.1).
I updated as Wolfgang suggested to version 1.1.2 and it works fine.

Many thanks to Wolfgang and Robert for the help!

Roberta

Hi Roberta,

I had a similar problem recently, and it turned out to be a matter of 
versioning between the GOstats package and GO package. There have been 
some changes in the way data is presented in the GO package, which 
required a tiny but important modification in makeGOGraph. Make sure to 
use the most recent versions of both, and let me know if that helps.

For me it works with
GO 1.6.8
GOstats 1.1.2

    Best wishes
     Wolfgang
