[BioC] problem with annaffy aafFunction function

[Kimpel, Mark William]

I am using annaffy to annotate some rat data. When using the aafFunction
in affaffy, all of the objects returned were "character(0)". I then
tried the function using the example code from the help page. I was
surprised to get the same result. Is there a problem here? Session info,
example code, and results below. Thanks. Mark

sessionInfo:

R version 2.2.0, 2005-10-06, i386-pc-mingw32 

attached base packages:
[1] "tools"     "methods"   "stats"     "graphics"  "grDevices" "utils"
"datasets"  "base"     

other attached packages:

"1.8.1"    "1.6.5"    "1.8.0"    "1.7-3"

Example code used:

if (require(hgu95av2)) {
         data(aafExpr)
         probes <- geneNames(aafExpr)
         functions <- aafFunction(probes, "hgu95av2")
         show(functions[6:10])
     }

Results:

An object of class "aafList"
[[1]]
An object of class "aafFunction"
character(0)

An object of class "aafFunction"
character(0)
