The following call to curl fetches me the information I want (as html) from a webserver:
curl -F list_fi...@snptxt -F html_output=on http://integrin.ucd.ie/cgi-bin/rs2cm.cgi The file snptxt is a plain-text file in my working directory with the following two lines: rs6598 rs123456 In R I try to replicate this with RCurl as follows: require(RCurl) postForm(uri="http://integrin.ucd.ie/cgi-bin/rs2cm.cgi", "list_file"="@snptxt", "html_output"="on") but the table that is supposed to contain my results is empty (table caption is Genetic Locations). The cgi script has apparently received the html_output=on information though. I get the same results on Linux and Windows -- sessionInfo() for both follows. Any pointers appreciated.
