Nested for loops
Hi, I have spent some time locating a quite subtle (at least in my opinion) bug in my code. I want two nested for loops traversing the above-diagonal part of a square matrix. In pseudo code it would something like for i = 1 to 10 { for j = i+1 to 10 { // do something } } However, trying to do the same in R, my first try was for (i in 1:10) { for (j in (i+1):10) { //

Find multiple elements in a vector
Hi, Given a vector, say x=sample(0:9,10) x [1] 0 6 3 5 1 9 7 4 8 2 I can find the location of an element by which(x==2) [1] 10 but what if I want to find the location of more than one number? I could do c(which(x==2),which(x==3)) but isn't there something more streamlined? My first guess was y=c(2,3) which(x==y) integer(0) which doesn't work. I haven't found any clue in the R

heatmap plot
Dear R community! I am trying to create a heatmap based on the following data. As you can see the diagonal (0,0 to 10,10) is always 0). If I run the heatmap command like i posted it I get a graph with horizontal lines. What is my mistake? > heatmap(activity.matrix, Rowv = NA, Colv = NA, scale="column", xlab="x Compounds", ylab="y Compounds",

Rounding error in seq(...)
Hi, Today I was flabbergasted to see something that looks like a rounding error in the very basic seq function in R. > a = seq(0.1,0.9,by=0.1) > a [1] 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 > a[1] == 0.1 [1] TRUE > a[2] == 0.2 [1] TRUE > a[3] == 0.3 [1] FALSE It turns out that the alternative > a = (1:9)/10 works just fine. Are there any good guides out there on how to deal

plot ᵒ C in graph axis label
Readers, I have tried to use a plotmath command to add the temperature degree sign (i.e. ?

Combining a greek letter and a newline on the same label
Hi, I would like to add a two-lines label consisting of: "Delta word1\n word2" (with Delta being the actual greek letter). However, when I try "expression(paste(Delta,"word1\nword2"))", I obtain the following display: "word1\n Delta word2". Do you have any idea on how to obtain the desired display?

randomForest question--problem with ntree
Hi, I would like to use a random Forest model to get an idea about which variables from a dataset may have some prognostic significance in a smallish study. The default for the number of trees seems to be 500. I tried changing the default to ntree=2000 or ntree=200 and the results appear identical. Have changed mtry from mtry=5 to mtry=6 successfully.

Building a big.matrix using foreach
Hi there! I have become a big fan of the 'foreach' package allowing me to do a lot of stuff in parallel. For example, evaluating the function f on all elements in a vector x is easily accomplished: foreach(i=1:length(x),.combine=c) %dopar% f(x[i]) Here the .combine=c option tells foreach to combine output using the c()-function. That is, to return it as a vector. Today I discovered the

R on Multi Core
Hi, Our discussions about 64 bit R has led me to another thought. I have a nice dual core 3.0 chip inside my Linux Box (Running Fedora 11.) Is there a version of R that would take advantage of BOTH cores?? (Watching my system performance meter now is interesting, Running R will hold a single core at 100% perfectly, but the other core sites idle.) Thanks! -- Noah

I tried d{\tau}, d\tau, etc., without any success Is it possible? How can I accomplish this?

Bold greek letters using plotmath
I'm trying to annotate some graphics using plotmath and finding out that the code I'm using isn't bolding the greek letters - it bolds the rest (once I adjusted the numerics to characters), it's just failing on the greek characters. Any suggestions welcomed. Jim Price. Cardiome Pharma Corp. Test code: plot(1:5, type = 'n') # The not bold version text(2, 2:4, cex =

evince not showing "greek" and "math" in *.pdf plots
This problem has bugged me for several years now, and our own IT staff has tried a few things, but then never cared enough to persist fixing it. It *is* a bug in evince, the standard pdf viewer on Fedora and IIUC also quite few other Linux distributions, and *not* a bug in R; hence I am asking for help/hints here. A very simple example:
