I seem to be experiencing the same problem with a large number of affy IDs.
Here are a few examples:

Here is an example
> ontoKLF4 = ontoCompare("224997_x_at", probeType = "hgu133plus2",
method="TIDS", endnode=GOIDS)
[1] "Starting ontoCompare..."
[1] "Number of lists = 1"
Error in as.vector(x, mode) : invalid argument 'mode'

I'm running R v 2.6.0 with 
attached base packages:
[1] tools     stats     graphics  grDevices utils     datasets  methods   base 

other attached packages:
[1] hgu133plus2_2.0.0   goTools_1.10.0      GO_2.0.0            annotate_1.16.0
    xtable_1.5-2       
[6] AnnotationDbi_1.0.6 RSQLite_0.6-3       DBI_0.2-4           Biobase_1.16.1 

any help would be greatly appreciated.
thanks,
Sebastien
