I have a new post up over at Fantasy Ball Junkie looking at the value of closers in H2H leagues from here on out. I simply simulated in the same way as the Stolen Bases and Home Runs articles from before. Saves are an interesting bunch, and it really...
I released inline 0.3.6 yesterday. This is a minor release which gives better R level errors when there is a compiler error. For example : > tryCatch( cxxfunction( , 'int x = 3 ; x+ ; return R_NilValue ; ' ), error = function(e) print(e$message)...
In this previous post, we’ve looked at displaying three dimensional data. One major problem is when there is a high density of data, it can be difficult to see what’s going on in a 3 dimensional plot. One way of looking at the data in more detail is to break it up. Take a look 
I am a contributor to the optmatch and the RItools packages for R. These two packages are separate, but complimentary. Both packages provide tools for adjusting observational data to exhibit “balance” on observed covariates. In a randomized control trial, treatment and control groups should have identical distributions over all covariates, observed and unobserved. Matching provides a...
A month ago I posted about “SURF”, the newly-established Sydney R user forum (R being an excellent open-source statistics tool). Shortly after publishing that post, I attended the inaugural forum meeting. While we waited for attendees to arrive, a few people introduced themselves, explaining why they were interested in R and how much experience they
A new release of RcppArmadillo is now on CRAN. RcppArmadillo makes it easy to write highly efficient and highly readable C++ code for linear algebra (based on Armadillo) in R extensions (using Rcpp for the interface). This release upgrades the include...

Red-R seems to have some interesting ideas behind it. Of course it needs some time to mature.
A most interesting paper by Adrian Raftery and Le Bao appeared in the Early View section of Biometrics. It aims at better predictions for HIV prevalence—in the original UNAIDS implementation, a naïve SIR procedure was used, based on the prior as importance function, which sometimes resulted in terrible degeneracy—, but its methodological input is about
