[BioC] HTTP POST in R, Unigene

[James Wettenhall]

Hi,

I am interested in performing an HTTP POST from within R, in
order to perform a non-interactive search on a database 
normally accessed via a website interface such as
Unigene:
http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=unigene

In the source code for the ll.htmlpage function in the annotate
package I can see how an HTTP GET is performed - with a
question mark after the URL.

But what if I want to immitate the following curl command (done
at the unix command-line) in R?  Note that the -d option stands 
for "data" which is used in the HTTP POST.

curl -d term=NIA15k%20H31 -o UniGeneResults.html 
http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=unigene

Can anyone tell me what R function I should be using, (if there 
is an appropriate one)?

Regards,
James
