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)?
