[BioC] PFAM family names

[Daniel Gatti]

I'm trying to get text descriptions of PFAM family names from the PFAM 
package.  I've tried to run the example code from the pfamAC2PDB help.

 > AC2DE <- pfamAC2DE()
 > head(AC2DE)
$PF00244
[1] "14-3-3 protein"

 > pfamAC2DE(ac=sample(names(AC2DE), 3))
Error in sample(names(AC2DE), 3) :
   cannot take a sample larger than the population when 'replace = FALSE'
 > length(AC2DE)
[1] 1
 > names(AC2DE)
[1] "PF00244"

It seems that the list contains only one value.  How do I get 
descriptions for all of the PFAM families?

Thanks,
Dan Gatti
