Dear sir/madame, I am currently writing a meta-analysis on the complication and reoperation rates of 5 different treatment modalities after a distal radius fracture. I was able to pool the rates of the 5 different rates using R...

The sample files are here: http://github.com/gjkerns/samplequiz It took me a shamefully long time to get this just right, and it's still not perfect (an extra space here and there, the indentation...). But the whole thing...

Though bigmemory, ff, and other big data solutions (databases, etc...) can help easily manage massive data, their data objects are not natively compatible with all the advanced functionality of R. Exceptions include lm and glm (both ff and bigmemory support...

I'm trying to improve my package documentation and tried out promptMethods() in R-2.10.0 (Linux 64-bit Ubuntu). It generates an Rd file with an extra \ before signature, such as: \item{\code{\signature(x = "matrix")}}{ ... } generating warnings...

The long-promised revision to bigmemory has arrived, with package 4.2.3 now on CRAN. The mutexes (locks) have been extracted and will be available through package synchronicity (on R-Forge, soon to appear on CRAN). Initial versions of...

Dear All, The latest version of IPSUR (last one for awhile) is now available on CRAN. What's New in 0.1-1: 1. Important bug fixes 2. Test of equality for several proportions... 3. Enter table for single proportion...

Hi, I am preparing a data package and using the minfiData package as a reference. The .idat files in extdata and the .rda file in data are both present in both the compressed tarball source and the installed copy directory...

Hello, I need help with this. Let's say that I have n features that I want to use to predict which class an observation belongs to. Using training data I try to do the following: > training$result <- as.factor...

The re-engineered bigmemory package is now available (Version 3.5 and above) on CRAN. We strongly recommend you cease using the older versions at this point. bigmemory now offers completely platform-independent support for the big.matrix class in...

Yes, Bryan put irlba up on CRAN. It works on either matrix or big.matrix objects, too. However (as Bryan would note) it is a pure R implementation and its performance could be greatly improved by moving much of the...

Ted, Simon may be biased, but I am not. I'm barely a few days into Rserve/FastRWeb and am blown away (and frustrated that I didn't have a good excuse to give it a try sooner). I'm...

Does the "legend" command work in the windows version of R? Here is the command that I'm using: legend(1,1,legend=c("G1","G2","G3","G4","G5","G6"),pch=array(1:6,dim=c (1,6))) When I...

Gabor makes my (minor) point with greater eloquence. I certainly am not arguing against the value of Rcpp, and I agree completely with Hadley on the inconsistencies if we're talking about .Call and SEXP, etc... > Nice document but it...

Hello, Having my own spatial weight matrix, I converted it to a listw format and calculated the Moran index. The codes are listed below: Wod_lw<-mat2listw(Wod) moran.test(mydata$Ties_processed,Wod_lw, randomisation=TRUE) However, after I...
