[BioC] postForm in RCurl

[Duncan Temple Lang]

Hi Ovokeraye

  Your script is  okay. It works for me.
Somehow the communication between the server and RCurl
fell apart at some point.
You should try it again now and see if it works now.
Otherwise, are you behind some sort of firewall? proxy? etc.?

While your query works, it gives no results in the table.

I simplified the query to just one disease.

 data = postForm("http://www.genome.gov/GWAStudies/#searchForm",
                   disease = c("Fasting glucose-related traits"),
                   submit = "Search")

 tbl = readHTMLTable(htmlParse(data, asText = TRUE), which = 5, header = TRUE)

and tbl contains the result.

  D.
