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.

Hi all, I want to conduct a cluster analysis with quantitative variables. More precisely, it concerns binary and non-ordered categorical variables. For such data, various similarity measures have been proposed, such as the Jaccard index or the simple matching index. So, is there a package such as mva or multiv in the case of quantitative variables? Could you indicate me reviews, papers or

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

Hello R users Would somebody know how to estimate survival from a frailty cox model, using the function survfit and the argument newdata ? (or from any other way that could provide individual expected survival with standard error); Is the problem related to how the random term is included in newdata ? kfitm1 <- coxph(Surv(time,status) ~ age + sex + disease + frailty(id,

Hello, in order to vectorize task (of plotting barplots), I use, as probably all R-folks, function apply() instead of for() loop. <R> testarr<-matrix(1:30, nrow=5) rownames(testarr)<-letters[1:5] colnames(testarr)<-LETTERS[1:6] apply(testarr,1,function(x) {x11(); barplot(x)}) #the funcion used is actually more compex, but it doesn't matter </R> Now, how I can propagate
