[BioC] Error in package goseq

[Joydeep Mitra]

Hi,

I am a grad student at Institute of Bioinformatics, University of Georgia, USA. 
I have been trying to use the bioconductor package goseq for go-term/pathway 
enrichment of my expression data.
Since my organism of interest isn't included in the goseq database, I am 
manually entering the data for gene lengths and categories following the 
directions in the vignette provided with the package. I have tried representing 
the gene-category mappings in both data frame and list formats as specified.
While the 'nullp' function worked fine for my data, when I run goseq() with the 
following command, I get an error message:



> eco1.gs<-goseq(DEgenes=eco1.de,pwf=eco1.pwf,gene2cat=ids.go.list)
Using manually entered categories.
Error in summary(map)[, 1] : incorrect number of dimensions





Here's my session info:

Has anyone else faced this problem in goseq? Any help is appreciated.

Thanks,
