Hi all, By default, the heatmap function gives an image with a dendrogram added to the left side and to the top. Is it possible to only add the dendrogram to the left side and let the order of the columns unchanged ? I tried heatmap(mat, col=rbg,Rowv=res.hclust$order,Colv=1:dim(mat)[[2]]). In this case, the order of the columns are unchanged but a dendrogram is added to the top. How can I

Hi all, Let Names a vector of chatacters. For example, > Names [1] "g 604 be-0 -p1 (602 matches)" "g 606 Phli-0 -p2 (517 matches)" [3] "g 608 alu-0 (659 matches)" I try to use gsub or grep functions for two problems : 1. First, I would like to delete all the characters between parentheses. [1] "g 604 be-0 -p1" "g 606 be-0 -p2" [3] "g

Hi all, I would like to call a C program from R function. I tried to use the .C() function without success. I need a very simple example (such as the hello program) to understand how it works. Could you give a such example? (I use the 1.7.1 Version of R with linux) Does it work in the case of a C++ program instead of a C programm? Best regards, Olivier --

Hi all, I would like to save the dendrogram of a hierarchical clustering. Let reshc the result of the fucntion hclust(). To save the dendrogram, I can use the function postscript: postscript(file="hc605.ps") plot(as.dendrogram(reshc),horiz=T,ylab="",main=" ") dev.off() Using the functions plot and as.dendrogram, it is possible to obtain an horizontal tree with

Hi all, When I start R, it gives mkdir: Ne peut cr?er le r?pertoire `/home/mart/tmp/Rtmp11729'.: No such file or directory (I specify that my home path is /home/mart and the R version is 1.7.1) How I have to configure R to use the directory /tmp instead of /home/mart/tmp ? What is utility of this directory tmp for R? Thanks, Olivier

Hello, I am using the 'regsubsets' function (from leaps package) to get the best linear models to explain 1 variable from 1 to 5 explanatory variables (exhaustive search). Is there anyone who can tell me on which criterion is based the 'regsubsets' function ? Thank you. samuel Samuel BERTRAND Doctorant Laboratoire de Biomecanique LBM - ENSAM - CNRS UMR 8005

Hi all, Suppose I have a vector x with numerical values. In y, I have a categorial variable : y<-c(1,1,..2,2,...30,30,30) x and y have the same length. I would like to compute the mean for x for the modality 1 to 30 in y. mean(x[y==1]),...,mean(x[y==30]) I do not want to use an iterative procedure such that for (i in 1:30).. Thanks for your help, Regards. Olivier. --

Hi I have a large dataset, containing a wide range of binary variables. I would like first of all to compute a jaccard matrix, then do a PCA on this matrix, so that I finally can do a hierarchical clustering on the principal components. My problem is, that I don't know how to compute the jaccard dissimilarity matrix in R? Which package to use, and so on... Can anybody help me? Alternatively
