Hi, how can I change a defined factor-variable? Like adding levels, renaming existing levels or merge several levels of a factor to one level? For example; following factor-variable is given: x <- factor(c("xyz1", "abc1", "xyz2", "abc2")) How can I add the level fgh? And how can I merge "xyz1" and "xyz2" to one level? And

Assume a C program invoked by .Call, that returns a list. Near the top of the program we allocate space for all the list elements. (It is my habit to use "xyz2" for the name of the R object and "xyz" for the pointer to its contents.) PROTECT(means2 = allocVector(REALSXP, nvar)); means = REAL(means2); PROTECT(u2 = allocVector(REALSXP, nvar)); u =

Hi all, I just start to learn llvm. I am trying to get the operand's name of some instruction that invokes a function field of a struct. While, I found in the result that there is a sequence number attached to the function field name. Below is an example: /******source code t2.c*******/ #include <stdio.h> void F(){printf("F\n");} void E(){printf("E\n");} void

Hi, Let's say that I have a set of column names that begin with the string "Xyz". How do I extract these specific columns? I tried to do the following: dataframe1[,grep("Xyz",colnames(dataframe1))] But it does not work. What is wrong with my expression?

I am currently working on surface plots (with R 2.0.1) and I want to improve the aspect of them. Having a typical 'cow-boy hat' surface [source: Spector (1994), p. 206]: pts <- seq(from = -8, to = 8, length = 50) cow <- function(x, y) { z <- sqrt(x^2+y^2) sin(z)/z } out <- outer(pts, pts, cow) sur <- persp(x=pts, y=pts, z=out, theta=45, phi=30) What I exactly wanted is:

Hello I am looking for a simple way to plot my data from a matrix (or data frame) using a 3rd column as category to code the data points. for example: xyz 543240 104230 15901 203241 25781 3042340 357891 405670 45780 50531 Ideally, I'd like 0 or 1 to correspond to a color but I'd settle for a symbol at this point.  I have tried working with pch but can't get it to work. Thanks Kat

Hello, I have my work on the nv vpe video decoder in a functional state. In case you didn't know this decoder accelerates mpeg2 video at the idct/mc level. I have verified that it works on nv40 hardware. I believe it works on nv30 hardware (and maybe some earlier hardware), but I cannot verify since I have none. I will reply with patches against the kernel, drm, ddx and mesa for

Hello list. I'm trying to rebuild the 2.6.9.67.0.20.EL kernel, but it fails even without modifications. How did I try it? Created a (non-root) build environment (not a mock ) Installed the kernel.scr.rpm and did a rpmbuild -ba --target=`uname -m` kernel-2.6.spec 2> prep-err.log | tee prep-out.log The build failed at the end: Processing files: kernel-xenU-devel-2.6.9-67.0.20.EL Checking
