[R] cluster package
Hi list, I am doing cluster analysis using the cluster package. I created a dendrogram using the function plot(agnes(myData)). When I try to change the sise of labels, it does not work. I tried cex = 1.5, etc. Nothing worked. Can anyone give me a hint on how to change the sise of the labels, as well as the sise of axes labels.

[R] malloc: vm_allocate(size=381886464) failed (error code=3)
Hi all, I am having memory allocation problem with my R 2.2.1 for Mac OS. The following is the error message that I get. I do not get this message if I break down the large dataset in to sub datasets. I think breaking up the dataset is not a sustainable solution in the long run. The data that I am analysing is essentially big, and it would be reasonable to do the analyis on the whole dataset without even considering to partition it. So I was really wondering if you could give me a clue about how to handle this problem. model6 <-lm(logintens~ factor (slide) + factor(ind) + factor(dye) + factor(id)*factor(l6) + factor(rep)-1, data=sample_data2) *** malloc: vm_allocate(size=381886464) failed (error code=3) *** malloc[387]: error: Can't allocate region *** malloc: vm_allocate(size=381886464) failed (error code=3) *** malloc[387]: error: Can't allocate region *** malloc: vm_allocate(size=381886464) failed (error code=3) *** malloc[387]: error: Can't allocate region *** malloc: vm_allocate(size=381886464) failed (error code=3) *** malloc[387]: error: Can't allocate region *** malloc: vm_allocate(size=381886464) failed (error code=3) *** malloc[387]: error: Can't allocate region Thanks for your help in advance Regards Mahdi -- --- Mahdi Osman (PhD) E-mail: [EMAIL PROTECTED] --- Echte DSL-Flatrate dauerhaft für 0,- Euro*! __ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
[R] Memory problem
Hi list, I am analysing a large dataset using random coefficient (using nlme) and fixed effects (using lm function) models.

[R] lme help
Hi list, I am fitting microarray data (intensity) model using the lme package in R environment. I have 5 fixed variables in the model. One of the fixed variables is genes. I am trying to get p-values for different genes. But I am getting only one p-value for all genes together. I can get a list of p-value when I run lm. Why can't this work in lme? My aim is to do multiple comaprison of all the genes that I have and I can only do this if I have a list of their p-vales I was wondering if you can help me solve this problem. That is getting a list of p-value for each gene in the model using the lme.

[R] post hoc analysis after anova
Dear list, This is a simple question but I spent an hour on it without success. So I sorry to bother you. I fit a linear model "lm" and then did "anova". My idea is to run multiple pairwise comparision for several factor variables (f1, f2, f3, f4 each with its own levels, say "0", "1", "3" etc )at the same time and get statistics for each factor's levels. The statistics I want is just the basic one such as mean standard error. I tried the "pairwise.t.test", but I could not do what I wnated to. I was wondering if anyone has idea about how I can accopmlish this task?

[R] glm
Hi, list, I have got a dataset on soil and plant. I would like to fit a "glm" to my data. My response variable is percentage data. That is percent of plant root length colonized by Arbuscular micorrhiza fungi. Because of the nature of my data, I am not quite sure whether gamma or gaussian distribution is suitable for this type of data. If I use gamma distribution, which link function is appropriate? I appreciate your suggestions very much. Thanks in advance!

[R] updating packages
Dear list, I have been trying to resolve the following problem for a couple of hours, but couldn't get around. I updated my R pacages from CRAN which went somoothly. However, updating HTML is not going well. I got the following error message: 1: Package R2HTML is in use and will not be installed. 2: Number of rows of results is not a multiple of vector length (arg 1) in cbind (pkgs, lib). This happend after I configured my xemacs init to use xemacs as GUI for R. The communication between my xamcs and R is going perfectly well and fantastic. I am wondering if anyone can give me a hint on why R2HTML is not updating itself.
