Hi Valerie -- curlPerform is expecting the url to be an option that is named, i.e.,
> myopts <-curlOptions(netrc=1) > url <- "http://www.omegahat.org/RCurl/testPassword/index.html"; > cat(curlPerform(url=url, .opts=myopts)) <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML//EN"> <html> <head> <title>Basic Password Test</title> </head> <body> <h1>Basic Password Test</h1> This is a test page. If you can read it, you have correctly supplied the password. <hr> <address><a href="http://stat.ucdavis.edu/~duncan";>Duncan Temple Lang</a> <a href=mailto:[EMAIL PROTECTED]><[EMAIL PROTECTED]></a></address> <!-- hhmts start --> Last modified: Sun Aug 1 13:57:44 PDT 2004 <!-- hhmts end --> </body> </html> (also curlPerform(url=url, netrc=1)) Martin Valerie Obenchain <[EMAIL PROTECTED]> writes: > Hello, > > I am having trouble getting the curlPerform function to authenticate > using the .netrc file.
