Folks, I'm running into something which looks like a bug in linearscan allocator. Of course I can't be 100% sure it's not some unobvious mistake on my part, so I'd like to hear your opinion. First, I attach two files -- LLVM asm and the asm for my target. The problem with assembler is: on line 171 it uses register gr2, which is copied from gr6 above, on line 161. The only

Dear R-users, I would like to maximize the function g above which depends on 4 parameters (2 vectors, 1 real number, and 1 matrix) using optim() and BFGS method. Here is my code: # fonction to maximize g=function(x) { x1 = x[1:ncol(X)] x2 = x[(ncol(X)+1)] x3 = matrix(x[(ncol(X)+2):(ncol(X)+1+ncol(X)*ncol(Y))],nrow=ncol(X),ncol=ncol(Y)) x4 = x[(ncol(X)+1+ncol(X)*ncol(Y)+1):length(x)]

Hi everyone. I want to solve the following problem. I have a data.frame and I create a dotplot using lattice. Then I want to use the grid-package to create a combined graphic which contains the dotplot as well as a textplot() (using package gplots) of the data.frame next to the dotplot. Example code: library(lattice) library(grid) library(gplots) xx <- data.frame(f=factor(rep(1:5, each=5)),

Hi all, for the data below I would like to 1. generate a dummy variable for each group "gr" of the same composition by people, then save each portion in a separate file, 2. compute the frequency of "1"'s in "x" for each person by group "gr". So, "mike" will have freq=2/3, as he has two "1" and one "0" in 3 groups.

When I create a lattice/Trellis type graph, I typically write a function that returns the graph, as in do.graph <- function(x, y, ...) { require(lattice) return(xyplot(y~x, ...)) } My question today is this: If I want two graphs on one page, one way of achieving it is to print the objects into defined areas, as in gr1 <- xyplot(rnorm(111) ~ runif(111)) gr2 <-

Hello! Is there an (semi)automatic way to save registers used by a function? For example, on my target I have to store ar0-ar4 and gr0-gr4, gr5, gr6. For now I just emit huge prologue code to push them all to stack -- even if they are not modified at all. Is there a way to tell LLVM which registers must be stored, and have it automatically issue pushes/pops? I can live with current design,

Dear expeRts, Why does na.blank=TRUE not replace the NA's in the following LaTeX table? x <- matrix(1:72, ncol=4, nrow=8) colnames(x) <- c("gr1.sgr1", "gr1.sgr2", "gr2.sgr1", "gr2.sgr2") rn <- apply(expand.grid(beta=c(0.25, 0.75), n=c(100, 500), d=c(10, 100))[, 3:1], 2, rmNames) x <- cbind(rn, x) # append columns containing the row labels

While adding support for branch instructions in my backend, I run into a trouble. The code to handle branches looks like: void visitBranchInst(BranchInst& BI) { BB->addSuccessor (MBBMap[BI.getSuccessor(0)]); if (BI.isConditional()) BB->addSuccessor (MBBMap[BI.getSuccessor(1)]); ........... BuildMI(BB,

I was starting to write a note to a prospective R-user and came to the point of explaining how to get useful introductory information on R. After mentioning the Into and the FAQs I went on to try to explain how to use a lot of the contributed information. However I realised that there seems to be no direct way to get to Other Publications or Contributed Documenation. The best I have seen is

Dear all, I get an error message when I use polr() in MASS.

Hi, perhaps this is a stupid question, but i need some help about Helmert contrasts in the Cox model. I have a survival data frame with an unordered factor `group' with levels 0 ... 5. Calculating the Cox model with Helmert contrasts, i expected that the first coefficient would be the same as if i had used treatment contrasts, but this is not true. I this a error in reasoning, or is it
