similar to: Memory Leak in OS X version of R?

Full_Name: David L. Van Brunt Version: 1.8-1.9 beta OS: OS X 10.3 Submission from: (NULL) (68.74.58.109) As posted on R-Help (after which another user replicated the problem): --------------- This is the conclusion from a prior thread ([R] " cannot allocate vector of length 1072693248") which ended with no other answer but that there must be a problem in the OS X version of R, or in

Andy; Well, that about does it.... I'm copying this one back to the list for the benefit of those who may hit this thread while searching the archives. Your changes to the code run just fine on the my Windows machine, but gives the vector length error on the G4 whether I'm using the OS X build of R (as in Raqua) or the X11 build (for Darwin). It is worth noting that I have nearly twice

When you have fairly large data, _do not use the formula interface_, as a couple of copies of the data would be made. Try simply: Myforest.rf <- randomForest(Mydata[, -46], Mydata[,46], ntrees=100, mtry=7) [Note that you don't need to set proximity (not proximities) or importance to FALSE, as that's the default already.] You might also want to use

Alternatively, if you can arrive at a sensible ordering of the levels you can declare them ordered factors and make the computation feasible once again.

From the RAqua faq just uploaded to CRAN (so it will take until tomorrow to appear) Panther notes After installing Panther (MacOSX 10.3) it turns out that package installation (either from sources or from binaries) can fail. If you get an error "like" this (this comes from source package installation) dyld: gcc version mismatch for library: /usr/local/lib/libiconv.2.dylib

I've built a version of RAqua that uses X11 TclTk and NOT AquaTclTk. http://www.economia.unimi.it/R/RAquaX11.dmg (15 MB disk image) The idea is that you: launch RAqua, launch X application (the X Server), and from inside R type x11() # just tt set DISPLAY to :0.0. Eventually close this window device, we don't need this. load(tcltk) quartz() demo(tkdensity) It works on my Panther

While playing around with panther I discovered (with surprise) that tcltk seems to work (even if not smoothly) with RAqua without first calling tkStartGUI. I switched back to 10.2.6 and it works as well. I think this is due to the "last minute" fix in RAqua now using idle timers because of too much cpu usage. Some "mouse" trick is needed though. If you want to test it you

It would seem that R 1.8 doesn't like the version of libiconv that Panther has installed. Can we compile this for Aqua ourselves or will there be a binary for we who upgrade sooner rather than later?

I've installed R 1.8.1 on OSX 10.3 (Panther) using the RAqua.pkg and all indications were that the installation was successful. However, after double clicking the R icon in the Applications folder, nothing appears to happen. The following message appears on the console: Mac OS X Version 10.3 (Build 7B85) 2003-12-11 08:45:31 -0500 prefs written dyld:

Hi, I've recently purchased PowerBookG4 (panther) and installed RAqua 1.8.1. I also installed gcc version 3.3 through Xcode tools. But, for some reason, I'm having a hard time getting gcc work with R. For example, I get the following error while installing Hmisc package. I would appreciate any suggestion to fix this problem. Thanks Kosuke * Installing *source* package

I'm running R 1.8.1 on a Mac with OS X 10.3 (Panther). The edit.data.frame( ) function doesn't seem to work. A window opens but I can't figure out how to navigate around it or to edit or add data to the data frame. It works fine on MS Windows. Is this just a limitation of Raqua? Anyone know of plans to fix it? Rich Simon Richard Simon, D.Sc. Chief, Biometric Research Branch Head,

Several ways: 1. Read ?randomForest, especially the `Value' section. 2. Look at str(myforest.rf). 3. Look at print.randomForest. If the forest has 100 trees, then the mse and rsq are vectors with 100 elements each, the i-th element being the mse (or rsq) of the forest consisting of the first i trees. So the last element is the mse (or rsq) of the whole forest. HTH, Andy > From: David

Hi all, I am working on Macos x 10.3 (Panther) to build a package consisting of C/C++ code that is called from R. In the C/C++-sources I use several commands to print info to the console: std::cout << "info" << endl; and: Rprintf("info\n"); Both work fine when R is run on the command line but neither works when running Raqau (I did check the preference boxes

Some user reported me that help.start() is no longer working on Panther under RAqua. I don't have this problem on my machine but a couple of users repoterd me this. Can you please make this small test an eventually tell me which is your system default browser? stefano

"classwt" in the current version of the randomForest package doesn't work too well. (It's what was in version 3.x of the original Fortran code by Breiman and Cutler, not the one in the new Fortran code.) I'd advise against using it. "sampsize" and "strata" can be use in conjunction. If "strata" is not specified, the class labels will be used.

I've been able to build a very primitive Aqua GUI for Darwin R. This version as minimum event handler support but at least you can drag around the quartz device. You need to download the RAqua.app.sit archive from http://www.economia.unimi.it/R/ You need to unstuff it and put inside your system Applications folder (i.e. /Applications) If you click on the RAqua icon nothing will happen

Sorry for the repost, but I've really been looking, and can't find any syntax direction on this issue... Just browsing the documentation, and searching the list came up short... I have some unbalanced data and was wondering if, in a "0" v "1" classification forest, some combo of these options might yield better predictions when the proportion of one class is low (less
