Hi, I'm running debian - upgraded fully to potato at the start of the freeze and added latest libgnome-dev before configuring. I tried compiling with gnome support with /usr/local/R/R-0.99.0/configure --with-gnome and got the following output: checking for gnome-config... /usr/bin/gnome-config checking if /usr/bin/gnome-config works... yes checking for orbit-config...

Hi, I've just upgraded my debian machine to the 2.1 libc6 libraries, and I started getting segmentation faults with R. I tried re-compiling and got the same problem. I checked with the dependencies for the binary package, and I have all the required libraries. Any ideas?

Hi, As a precaution against all the computers here (Griffith University, Australia) going down with the Y2K bug, all the computers are going down. The site that the R archives are on will be down for a number of days over the new year, and the machine which actually creates the HTML archive files will be down for longer. Apologies for the disruption. ---- Robert King, Australian Environmental

I don't want to re-invent the wheel, and I'm trying to code up something that does a Nelder-Mead simplex method to minimise a non-linear objective function. (I'm porting something I originally wrote in matlab, using the optimisation toolbox funciton fmins). Is there already something available to do this included in R? Do people have suggestions on the best way to do this? Thanks,

In July of 1999 Douglas Bates invited R users to implement an algorithm for non-negative least squares based on Bates and Wolf, 1984: Communications in Statistics, Part B 13:841-850. <http://www.ens.gu.edu.au/robertk/R/help/99b/0058.html> I'm wondering if anybody has implemented this or something similar so I won't have to reinvent the wheel. Thanks! Bob Abugov

Dear /Bill Paterson, while trying to find a way to convert SAS code into R, I came across your one time e-mail message (http://www.ens.gu.edu.au/robertk/R/help/99b/0908.html). I'd appreciate to learn if anything came out of this, or any suggestions. Thank you in advance, Mehmet Somel / -- Mehmet Somel Max Planck Institute for Evolutionary Anthropology Department of Evolutionary

HI, Dear Andy, I run the RandomFOrest in R, and get the following resutls in variable importance: What is the meaning of MeanDecreaseAccuracy and MeanDecreaseGini? I found they are raw values, they are not scaled to 1, right? Which column if most similar to the variable rel.influence in Boosting? Thanks so much! > fit$importance 0 1

Hello folks, I can't make R use the GNU-Readline-library. However, - I have run configure with --enable-readline and - configure *has found* the library. My Linux distribution is SuSe, July 1998. I'm using Kernel 2.0.25. I was told by Douglas Bates (r-devel), that this problem between R and (probably) SuSe was discussed before on this list. Can someone tell me how I can make R use

Thank you Brian Ripley, Gardar Johannesson, and Marcel Wolbers for your prompt and friendly help!

Hi, I am trying to assemble a three-way contingency table examining the presence/absence of mussels, water depth (Depth1 and Depth 2) and water velocity (Flow vs. No Flow). I have written the following code listed below; however, when run the glm I get the following message, "Error in model.frame.default(formula = Count ~ MP + wd + wv, drop.unused.levels = TRUE) : variable lengths differ

Hi R users, I am trying to use the optim function to maximize a likelihood funciton, and I got the following warning messages. Could anyone explain to me what messege 31 means exactly? Is it a cause for concern? Since the value of convergence turns out to be zero, it means that the converging is successful, right? So can I assume that the parameter estimates generated thereafter are reliable MLE
