First off: R> fortunes:::fortune("yoda") Evelyn Hall: I would like to know how (if) I can extract some of the information from the summary of my nlme. Simon Blomberg: This is R. There is no if. Only how. -- Evelyn Hall and Simon 'Yoda' Blomberg R-help (April 2005) R> Secondly, what you ask is necessarily rather OS-dependent. So of course it can be done, but probably in way that depend on your local circumstance. Thirdly, and to make this a little more helpful, I frequently use the RSQLite package to cache data across sessions and invocations. For a large example, consider the CRANberries feed (http://dirk.eddelbuettel.com/cranberries/) which stores in SQLite what the the state of the (CRAN) world was the last it got woken up by crontab. I also have a few smaller ad-hoc things at work that do similar things. Depending on your local circumstances you may make this 'cache' of stateful information read or read/write, make it a file on NFS or CIFS or WebDAV, make it a database that can be read as file or over sockets and so. And Yoda still rules.
