How can I insert mathematical expressions for variable names in a lattice parallel plot? I tried to implement mathematical expressions in varnames, however, without success. For example, neither parallel(~iris[1:4] | Species, iris, varnames=c("P[Width]", "Petal[length]", "alpha[Width]", "Sepal[Length]")) nor parallel(~iris[1:4] | Species,

Hi, I tried to install R packages required for the GRASS-R interface by using the following command (copied from http://www.geog.uni-hannover.de/grass/statsgrass/grass6_r_install.html): /install.packages (c("sp", "spgrass6","rgdal","maptools"), dependencies =TRUE)/ rgdal package was installed successfully; There were problems to find 'sp' and

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, 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 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

"Writing R Extensions" says {quotes} If you have a crash which gives a core dump you can use something like gdb /path/to/R/bin/exec/R core.12345 to examine the core dump. If core dumps are disabled... {unquotes} sadly it doesn't go on to say how to enable if core dumps are disabled. I understand that in bash I need to do $ ulimit -c unlimited but this doesn't seem to

Hi all, Let Names a vector of chatacters.

Hi, We re doing backups of all filesystems to a dedicated server using "rsync -x". Now, the latest CentOS versions (5.7/6.x) come with rsync-3.0.6 instead of rsync-2.x. That's nice but unfortunately it doesn't do the same as 2.x in certain situations. The problem is with the -x option, which does not delete content under a mount point anymore. It was my impression that this is

Dear all, I've just downloaded R.12.0 from CRAN (http://cran.r-project.org/bin/windows/base/release.htm). I am unable to find RGUI.exe as well as Rterm.exe.
