[R] object is not subsettable

[Radek Blatny]

Dear colleagues,
I've just come across a problem with the following command which is a  
part of the "metaOverview.R" code file provided as an monography- 
accompanying file at
http://www.bioconductor.org/docs/mogr/metadata:

##################################
R>  hasChr <- eapply(GOTERM, function(x)
+              x[grep("chromosome", Term(x))])

Error in x[grep("chromosome", Term(x))] : object is not subsettable
##################################

I have run the command in the (PPC) Mac OS X R 2.4.1 and (AMD Ubuntu)  
Linux R 2.4.0 with the same result so it shouldn't be any  
distribution-dependent problem. Obviously the "metaOverview.R" is not  
up-to-date since I had few problems before as well (e.g. that a  
function is in another package in BioC 1.9 etc.) but I was able to  
"repair" everything myself. However, this one I don't understand.  
Anyone can help? Some classes have changed?!

Best regards, Radek Blatny
