While designing an fMRI experiment, I ran into the problem that the mouse pointer disappears as soon as you start typing on a mac. In itself it is actually a handy feature -- hiding the mouse pointer makes sense as long as you’re typing -- but no...
While developing some new simulation code with S4 system I stumbled upon some big difficulties in terms of computational efficiency. That lead me to diging into archives of Rhelp and Rdevel looking for clues. I found some interesting threads that address almost exactly the same problems that I do. Read for yourself here and here, 
I have wrote about my experience with jags here. Martyn Plummer has updated jags recently and now jags can get as he claimed. Jags is fast and its source code is more manipulable (It's written in C++).I and Masanao wrote a package, R2jags, for runnin...
JAGS 1.0.2 is now out. This is a patched release for the stable version, so there are no major changes in library functionality. The major changes are: Memory leaks fixed. The rjags package now runs on Windows. A binary version … Continue reading →
Working on top of someone else’s code at work a couple of weeks ago I stumbled upon a piece of SAS code that went like this: View Code SAS1 2 3 length check 3; ... check = Name = 'Netter' Being raised in the land of open-source and having programmed in R since I was
In a recent post to r-sig-ecology, Mike Colvin suggested the following to capture errors within a loop:for (i in 1:1000){fit<-try(lm(y~x,dataset))results<- ifelse(class(fit)=="try-error", NA, fit$coefficients)}
R has a new platform-R-Forge-that enables developers and users to communicate with each other. More importantly, it is a version control platform that enables different developers to keep track on what others have been working on. So that ideally, if...
