Re: [R] R Memory Issues
Dear Emiliano: When they say to read the posting guide, mostly they mean read the posting guide. But I'll tell you the short version. 1. Include a full runable R program that causes the trouble you are concerned about. Include the data or a link to the data, usually the smallest possible example is what they want. They don't want 1000 lines of your dissertation project, they want 10 lines needed to produce the problem you are concerned about. The point here is this: Don't make people guess about what commands you ran or what your data actually was. You are going to get the attention of these folks one time, and you waste it by not reading the guide and not giving the full details. 2. Include the output from sessionInfo() whenever you ask a question of this sort. sessionInfo() R version 2.15.0 (2012-03-30) Platform: x86_64-pc-linux-gnu (64-bit) locale: [1] LC_CTYPE=en_US.UTF-8 LC_NUMERIC=C [3] LC_TIME=en_US.UTF-8LC_COLLATE=en_US.UTF-8 [5] LC_MONETARY=en_US.UTF-8LC_MESSAGES=en_US.UTF-8 [7] LC_PAPER=C LC_NAME=C [9] LC_ADDRESS=C LC_TELEPHONE=C [11] LC_MEASUREMENT=en_US.UTF-8 LC_IDENTIFICATION=C attached base packages: [1] stats graphics grDevices utils datasets methods base I can tell you my best guess about what is wrong: I suspect you have a corrupted R install. If you had given us the full working code, I could have tested that theory. But, alas, I can't. Why do I think so? I've taught a course this term with 45 students and about 1 time per week, a student would turn up with that can't allocate vector... error you see. On Windows, sometimes it seems the problem is due to installing R as an administrator and then trying to update some packages as a non-administrator. In one really frustrating case, student has installed car both as admin and as the user, and the one that was at the front of the search path was damaged, but we kept removing and re-installing the other one and nothing was fixed.
