To reproduce, load goseq followed by dplyr and call the "goseq" function.

Example output:

Error in UseMethod("select") :
  no applicable method for 'select' applied to an object of class
"c('GODb', 'AnnotationDb', 'envRefClass', '.environment', 'refClass',
'environment', 'refObject', 'AssayData')"
Calls: render ... withCallingHandlers -> withVisible -> eval -> eval ->
goseq -> select


Unloading dplyr resolves the issue:

    detach("package:dplyr", unload=TRUE)

Tested in Bioconductor-devel (3.0) + goseq-svn (92448 2014/06/26).

There is probably a better way to resolve this, but a possible solution is
to be explicit with the namespace:


GOnames=AnnotationDbi::select(GO.db,keys=pvals$category,columns=c("TERM","ONTOLOGY"))[,2:3]
