Dear list, could someone point me to the right command to subtract 2 columns in a data.frame. Might be a bit embarrassing question. But I cannot figure out how to do this simple command in R. Thanks, Ulrich -- __________________________________________________ Ulrich Leopold MSc.

Dear list, could someone point me to the normal score transform and it's use in R? I would like to transform my data with normal score transform, do some geostatsitical predictions and would like to transform the estimated values back including the estimation variance. Any suggestions? Ulrich -- __________________________________________________ Ulrich Leopold MSc. Department of

Hi, I have the following function: TEST <- cbind(Pox0t30.stone.1990.2000, sqrt(apply(Pox0t30.stone.1990.2000[,2:11], 1, var))) In rhe resulting Object TEST the added column is titled: sqrt(apply(Pox0t30.stone.1990.2000[,2:11], 1, var) I would like to change it to a sensible variable name like PoxMean. How can I incorporate this into the above function? Ulrich --

Dear list, I have a problem to install the GRASS_0.1-4.tar.gz on RedHat7.1 Linux. The gmake5 is missing. But I am not quite sure what it is? Is it a gnu version of MAKE? I could not locate it on my system and I do not know what is really meant. Any experience?

Dear list, I am using R 2.1.1 on a Fedora 3 Linux, 32 bit PC. If I compute the aggregated mean and the standard deviation I get standard deviation values for factors where the mean was not computed. It seems to me that this is somehow related to the NA values. But I don't quite understand what is going wrong? Could it be related to the data import already? Some of the imported data got the

Dear list, I would like to make a comment how to solve the X11 font problem under SuSE Linux (9.0) when you get the message: "X11 font at size 16 could not be loaded". After having modified /etc/X11/XF86config as root (see below) you have to run 'SuSEconfig' as root as well else nothing might be changed in the X-Server. After that no further messages should appear. HTH,

I noticed that the statically linked ogg/vorbis libraries for Windows are multithreaded. I want to link them into a non-multithreaded application, so I'm considering recompiling them to use the non-multithreaded C runtime. Is this feasible, or do libogg and libvorbis rely on multithreading? <p>--- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage:

Dear list, how can I write the following two lines in one function: > Pox2 <- ave(lsk0t50$Pox2, lsk0t50$ProfN, Fun=is.na(lsk0t50$Pox2)) > Pox2 <- data.frame(Pox2) The following does not work: > Pox2 <- data.frame(Pox2 <- ave(lsk0t50$Pox2, lsk0t50$ProfN, Fun=is.na(lsk0t50$Pox2))) > names(Pox2) [1]

I was surprised, given the vector-ish nature of R, to see that (according to my CPU meters) there doesn't seem to be any obvious multithreading in R. Are there any plans to change this?

Hi all, I was looking at the profile for a tool I’m working on, and noticed that it is spending 10% of its time doing locking related stuff. The structure of the tool is that it reading in a ton of stuff (e.g. one moderate example I’m working with is 40M of input) into MLIR, then uses its multithreaded pass manager to do transformations. As it happens, the structure of this is that the parsing

Hi. I need to execute a function from within a GUI. This seems to be no problem but this function takes about 4 minutes to finish, which means the application doesn't react at all, while the function is running. Can I execute a function as a separate Thread, while keeping control(e.g. a reference) of it at the same time? If not, how do this with a class containing this function? thanks,

Dear list, I would like to rename an object as follows: SimLUall <- matrix(c(0,1,0,0, 1,0,0,0, 0,0,1,0, 0,0,0,1),nrow=4, ncol=4) j <- 2 SimLUall2 <- SimLUall and j The value of j should be assigned automatically to SimLUall. How can I achieve this? Regards, Ulrich
