I have encountered a problem with merge() that appears to be a bug. Here's an example to illustrate it. > tmp1 <- data.frame(a=letters[1:3],b=LETTERS[2:4],x=1:3) > tmpa <- expand.grid(a=letters[1:4],b=LETTERS[1:4]) > tmpm.1 <- merge(tmpa,tmp1) > tmpm.2 <- merge(tmp1,tmpa) Error in "names<-.default"(*tmp*, value = vnames) : names attribute must

I'd like to have two packages with S4 classes with the same name but different implementation. To that end I create a package tmpA with setClass("A", representation=representation( x="numeric"), sealed=TRUE) setClass("B", representation=representation( x="numeric")) B <- function(...)

### I got bit again by the same bugs I wrote about a year ago. ### The bugs are related to matrices and arrays of lists. ### 1. There is a clear inconsistency in how R handles two ### functionally equivalent statements. ### array() is able to take a list and create a matrix. ### matrix() is unable to create that matrix. > vector("list", 2) [[1]] NULL [[2]] NULL >

Dear R useRs, i have the following code to compute values needed for a contour plot ############################################################ "myContour" <- function(a, b, plist, veca, vecb, dim) { tmpb <- seq(0.5 * b, 1.5 * b, length=dim) tmpa <- seq(0.5 * a, 1.5 * a, length=dim) z <- matrix(0, nrow=dim, ncol=dim) for(i in 1:dim) { for(j in 1:dim)

Greetings all, I am getting this error that is driving me nuts... (not a long trip, haha) I have a set of files and in these files I want to calculate ttests on rows 'compareA' and 'compareB' (these will change over time there I want a variable here). Also these files are in many different directories so I want a way filter out the junk... Anyway I don't believe that this is

This is a follow-up on the discussion originally posted on the R-devel list ( http://tolstoy.newcastle.edu.au/R/e4/devel/08/06/1901.html ), as I have encountered the exact same issue mentioned in Martin's email. Here is a simplified version of my problem: ##================================================================= ## I created a package, say, "tmpA", with a NAMESPACE with

Dear R users, I am a beginner in R. I have 506 text files (data frame) in one folder namely DATA. The files are called A1 to A253 (253 files) and B1 to B253 (another 253 files). Each file has two columns; V1 (row number) and V2 (the value for each row name). Now I would like to add the values of V2 in each A-file with its relative value in B-file and save it as a new data frame named as C (e.g. C1

libvorbis does not currently have any simd/vectorization. Following patches add generic framework for simd/vectorization and on top, add ARM-NEON simd vectorization using intrinsics. I was able to get over 34% performance improvement on my Beaglebone Black which is single Cortex-A8 based CPU. You can find more information on metrics and procedure I used to measure at

I just want to encrypt a string submitted through a form before saving it to the DB. And then decrypt it again when I need to retrieve and use it. Im trying to use the OpenSSL::Cipher library. I have the following module for encryption/decryption [code] require ''openssl'' module AESCrypt # Decrypts a block of data (encrypted_data) given an encryption key # and an
