similar to: adding a method to the dist function

Hi, is there a way to reference to a data object without copying it? For example I have a huge matrix called dist and I want two objects obj1 and obj2 to have a memeber dist that points to the matrix, but I don't want, for memory reasons, to copy the matrix twice. As far as I understand the following code will generate three copies of my data: dist <- some_code_that_generates_data

Hi, I was checking the source code to the function combn that "generates all combinations of the elements of 'x' taken 'm' at a time.", because I wished to modify it. I have a doubt about a statement. This is the main loop. ._1 <- 1:1 nmmp1 <- n - m + ._1 while (a[1] != nmmp1) { if (e < n - h) { h <- ._1 e <-

Hi, I am trying to produce incremental plots directly using the pdf device. I mean that I want to produce a plot, save it in a pdf file, then add details and save the new plot in a new file, and so on. Before I used to do this with x11, by just adding graphics to a plot and then using dev.copy2eps at the right times for each eps figure. Now I want to do this in batch mode and the x11 device is not

Hi all, I created a data frame with three factors, plus the response that looks like this: x1 x2 x3 y a 1 1 0.3 a 2 1 0.1 b 1 1 0.4 c 4 3 0.1 ... I would like to analise the effect of two of them, keeping the third fixed (I already know the effect of the last). The reason why I don't create several data frames for each value of the thirs factor is simply convenience (I'd like to be able

Hi all, I would like to add phonetic symbols in my figures. Usually I typeset my documents in LaTeX and I use the tipa [1] package to get International Phonetic Alphabet (IPA) fonts. So, my problem would be solved if I could insert LaTeX commands in the text() function (I guess at least). I would like to avoid using psfrag (that is, inserting a string in the eps figure and then substituting it

Hi, I am trying to create a plot and save it as pdf to the file file1.pdf, then add some details and save the new plot as file2.pdf. I would like to avoid repeating all the instructions needed to create file1.pdf when I create file2.pdf. This is what I have tried: pdf(file="file1.pdf") plot(1:10) dev.copy(pdf,file="file2.pdf") points(2,3) dev.off() dev.off() When I run

Hi, I need to call an R program from Sas.

Hi list, Here is the idea. I am running a domU out of a partition on a USB drive. I use the other partition to store the domU state. Then I carry this USB key to my office and restore the VM at the point where I left it. Thus I am trying to use xen''s virtualization to carry my desktop on a USB key. I have put up a web page explaining the details and a script to prepare the USB key.

Hello; I wrote this simple loop pass to collect the number of instructions in each loop of the program. The code is as follows- #define DEBUG_TYPE "loopinst" #include "llvm/Pass.h" #include "llvm/Analysis/LoopPass.h" #include "llvm/Support/raw_ostream.h" #include "llvm/ADT/Statistic.h" #include "llvm/Instructions.h" #include

Hi; I was playing with the -lda pass of LLVM on the following program- #include <stdio.h> void main() { int a[10]; int i; for(i = 0; i < 4; i ++) { a[i] = a[i-1]+1; } } I run the following commands - clang a.c -emit-llvm -S opt -analyze -stats -lda a.s The output is - Printing analysis 'Loop Dependence Analysis': Loop at depth 1, header block: %for.cond Load/store

Hello; I was planning to add a new instruction to the LLVM IR (and later to MIPS backend) for TLS(Thread level speculation) support. For this I tried to follow the steps described in http://llvm.org/docs/ExtendingLLVM dot html#instruction. But I could not find any llvm/lib/AsmParser/Lexer.l and llvm/lib/AsmParser/llvmAsmParser.y file in both the svn repository and the source code downloaded
