Hi, How do I access the loop variables in a loop. for(i = 0; i < N; i++) for(j = 0; j < M; j++) A[i][j+k] = i + j; Is there anyway for me to know that in A[i][j+k], i & j are loop variables whereas k is not!

Hi, I am new to LLVM. I want to go through all loops in a function. I see that there is a LoopPass manager that I can use. But that is not much of help, as I want to get the order of loops in CallGraphSCC order, hence I visit each function and then just want to go over the loops.

...seen here: > Ecdf (~Y|X2, groups=X1, data=x) > Ecdf (~Y|X2, groups=X1, data=x, label.curves=FALSE) Hence the question: Is there a robust function which can ignore such degenerate (and/or "near" degenerate) cells and be able to plot the rest. Any help is certainly appreciated. -- Prasenjit PS: [*] Ow I could spend a day/two to hack panel.Ecdf and/or prepanel.Ecdf for the purpose :( But making sure that the hacked code is bug-free would be more time consuming ;)

...this list as a proxy for "r-sig-linux"! Is there anything analogous to `basename $0` (more importantly, "$0") of bash in R? Of course, this only makes sense in either BATCH mode or source() or shebang scripts (e.g using littler or Rscript)? Thanks for being considerate ;) -- Prasenjit

OK, here is the issue: I have a graphcis device (say X11) which I can set as active by dev.set(n). Is there ANY way to identify/infer whether this X11 device was obtained from a lattice function (like xyplot, levelplot...) or a standard function (like plot, scatterplot,...). A related question is whether plot.new (or frame) was called to obtain this graphics device... Thanks. PK

Hi all, Using xyplot I want to print to Y variables (y1, y2) versus X, conditional on the group. How can I obtain a line (type="l") for one relationship (ie. y1 ~ x) and points (type="p") for the other (y2 ~ x) ? library(lattice) # create some sample data df<-data.frame(group=as.factor(c(rep("a",4), rep("b",4))), # grouping variable for conditional

Hello List, I would like to connect to a postgreSQL database on a remote server and I am wondering what is the best package to do that. I have just installed RpgSQL, RPostgreSQL, Rdbi and RODBC. The handiest to me is RPostgreSQL but I don't see how to connect to a remote server with it. For sure I can connect to remote server with RODBC, but since I am on a Mac OSX 10.6, I have quite

I don't mind using sudo apt-get update/upgrade/install buit I get into crazy loops (hours) that clearly can't be trusted. But when I use Synaptic (reload/mark for install R-base) every time I get some list of things things it want to install as well and syas "Mark" which it does not do and when I go forward with the Synaptic install of R-base I get this (and abort) every time:

Hello, Dirk (and everybody): I have Ubuntu on some systems and I notice there's a very nice thing you do with your R packages. The system is setup so that packages installed from deb go into /usr/lib/R, while packages built from scratch by root go into /usr/local/.., and if the user runs install.packages(), then it gets dumped into the user's own account. I'm much more familiar with

Hi, I have two matrices, A (axd) and B (bxd). I want to get another matrix C (axb) such that, C[i,j] is the Euclidean distance between the ith row of A and jth row of B. In general, I can say that C[i,j] = some.function (A[i,], B[j,]). What is the best method for doing so? (assume a < b) I have been doing some exploration myself: Consider the following function: get.f, in which,

Hi, I've actually run R quite a bit in Windows. I've had a release 8.04 of Ubuntu running a laptop for 3 days now. After struggling for much of that time to install R, I finally figured out that Dell shipped with the sources.list obsolete or just plain wrong. So I finally got it installed last night (for some reason v2.6.2, not v2.9.x). This morning I was able to download and install
