[R] problems with memory in Mac
Dear friends, I am having some doubts about the amount of memory that is being used by R in my Mac (MacBook Pro, 2Gig). Is there a way to increase the amount of memory used? When I type: mem.limits() the result is: nsize vsize NANA and I can't change it, tough my computing in R isn't using all the memory at it's disposal.

[R] matrix similarity comparison
Good morning to you all, I have a problem with a set of matrices that I want to compare. I want to see the similarity between them, and to be able to extract the differences between them. They have all the same number of columns and rows, and correspond presence absence data: for example: m1 - matrix(c(1,0,0,0,1,0,1,1,1,1,1,1), 3,4) m2 - matrix(c(1,0,1,0,1,0,0,1,0,1,0,1), 3,4) I tried with the function cor2m() [package=edodist] but it didn't worked and my matrices are much bigger than the ones from the example.

Re: [R] matrix similarity comparison
Let me see if I can explain my problem better, I have: m1 - matrix(c(1,0,0,0,1,0,1,1,1,1,1,1), 3, 4) rownames(m1) - c(station1, station2, station3) colnames(m1) - c(A,B,C,D) m2 - matrix(c(1,0,1,1,1,0,1,1,0,0,1,1), 3, 4) rownames(m2) - c(station1, station2, station3) colnames(m2) - c(A,B,C,D) ... and I want to: - find the correlation between the two matrices - for each station, extract the names of the columns that don't match in the two matrices Thanks for the previous comments, Carlos -- Carlos GUERRA Gabinete de Sistemas de Informacao Geografica Escola Superior Agraria de Ponte de Lima Mosteiro de Refoios do Lima 4990-706 Ponte de Lima Tlm: +351 91 2407109 Tlf: +351 258 909779 Reclaim your Inbox...!!! http://www.mozilla.org/products/thunderbird/ __ 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 and provide commented, minimal, self-contained, reproducible code.

Re: [R] Off topic:Spam on R-help increase?
Dear Mark, If you are using an email program like thunderbird or any other you can filter your emails by key (not very amusing) words at the source. Best regards, Carlos Mark W Kimpel escreveu: me too. Over 50% of messages are spam. I also noted the same thing on ESS-help.

[R] Problems with principal components analysis PCA with prcomp
Dear friends, I am beginning to use R software in my academic research and I'm having some problems regarding the use of PCA. I have a table with 24445 rows and 9 columns, and I used the function prcomp() to do the analysis. Working with an example…: x-read.table(test.txt, header=T) row.names(x)-x[,1] x-x[,-1] require(stats) pca-prcomp(x, scale=T) names(pca) ## here begin my problems… know what…??## My questions are: 1. How can I group my samples (rows) in a graphical way? 2. How can I extract the samples related to each group? …or… How can I create a new column with n values corresponding to each group created? 3. Is it possible to extract/export the information in an object into a file with a dbf extension (e.g. test.dbf)?
