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.

Dear RHelp-list, ?? Using dplyr and the group_by approach on a dataframe, I want to be able to apply a specific action according to the group name. The code bellow works, but I am not able to write it in a more esthetic way using dplyr. Can somebody help me to find a better solution ? Thank you Best regards Laurent df_test <- data.frame( x1=1:9, x2=1:9,

Laurent: As I don't use dplyr, this won't help you, but I hope you and others may find it entertaining anyway. If I understand you correctly (and ignore this if I have not), there are a ton of ways to do this in base R, including using switch() along the lines you noted in your post. However, when the functions get sufficiently complicated or numerous, it may be useful to store them in a

Although there may well be many ways to do what is being asked for with the tidyverse, sometimes things are simple enough to do the old-fashioned way. The request seems to have been to do something to all rows in ONE specific group but was phrased in the sense of wanting to know which group your functionality is being called in. What grouping gains you is more worthwhile if you are interested in

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,

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,

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

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
