How do I use cookies with RCurl?

Question

I am trying to write an R package that accesses some data via a REST API. The API, however, doesn\'t use http authentication, but rather relies on cookies to keep credential

Answer 1

My bad. Neal Richter pointed out to me http://www.omegahat.org/RCurl/RCurlJSS.pdf - which better explains the difference between cookiefile and cookiejar. The sample script in the question actually does work. But it only writes the file to disk when it is no longer being used.
