Thanks in advance.

Hi,
I have a list of IPI gene IDs. I want to find out whether there is a
package which can map the gene ontology to these IPIs, and plot the
pie chart to demonstrate the molecular function distributions.
The input is like the following gene IPI IDs:
IPI:IPI8860.1|SWISS-PROT:Q9BXJ4-1|TREMBL:Q

Hi,
In perl, to get a substring matching a particular pattern can be
implemented like the following example:
$x = ".txt";
if ($x=~ /(.*?)\.txt/){
$prefix = $1;
}
So how to do the same thing in R?
Can someone provide me the code sample?
Thanks much in advance.
