Hi, this is due to the R.utils library. Interestingly, others reported this yesterday. There are three different ways to get around the problem right now: 1) Exit R so it does not call .Last() by quit(runLast=FALSE), 2) load the R.utils package and then exit via quit() as usual, or 3) remove the faulty .Last() function by rm(.Last). (Thus, you don't have kill the R process).
Brief explanation: If you load the R.utils package, it will modify or create .Last() so that finalizeSession() (defined in R.utils) is called, which in turn calls so called registered hook functions allowing optional code to be evaluated "whenever" R exists, cf. http://tolstoy.newcastle.edu.au/R/devel/05/06/1206.html. So, if you exit R and save the session, this .Last() function will be saved to your .RData file. If you then start a new R session and load the saved .RData, that modified .Last() function will also be loaded. However, if you now try to exit R again, .Last() will be called which in turn calls finalizeSession() which is undefined since R.utils is not loaded and you will get the error that you reported. I'm testing out an updated version of R.utils (v 0.8.6), which will not cause this problem in the first place, and will fix the problem in "faulty" .RData. I will put in on CRAN as soon as I know it has been tested thoroughly. In the meanwhile, you can install it by: source("http://www.braju.com/R/hbLite.R";) hbLite("R.utils") To fix an old faulty .RData file, start R in the same directory, then load the updated R.utils (which will replace that faulty .Last() with a better one), and then save the session again when you exit R. When you do this you will see "Warning message: 'package:R.utils' may not be available when loading", which is ok. That should fix your problems. Let me know if it works Henrik (author of R.utils) On 2/27/07, Bhanu Kalyan.K <[EMAIL PROTECTED]> wrote: > Dear Sir, > > The R interface that i am currently using is R 2.4.1( in Win XP).
