Thanks, Adam!

That's promising.

But I'm looking at the list of supported methods here: http://cran.r-project.org/web/packages/Rlabkey/Rlabkey.pdf

and have successfully used the getSession() method, which relies on the above mentioned .netrc file to work, and I have not seen in its signature any mentioning of the session id. Is it through a different mechanism?

The R script is indeed passed the context from the server, part of which are:

labkey.sessionCookieContents : chr "3F074B27BA3E82380731988BCAEE0D56"

and

labkey.sessionCookieName : chr "JSESSIONID"

Is the first item, what you refer to as the current user's Labkey session id?

Could you, please, elaborate on exactly how does one make Rlabkey calls using this session id to authenticate to the server?

Thanks.
