I’m not always careful in citing all the R packages I use. R actually has some rather nice built-in mechanisms to support this, so I really have no excuse. Here’s some quick examples: To cite the ouch package in publications use: Aaron A. King and Marguerite A. Butler (2009), ouch: Ornstein-Uhlenbeck models for phylogenetic comparative
I was writing comments on the blog post A proposal for a really fast statistics journal, and I realized the comment box was too small to write down my ideas. I like the proposal a lot, and I feel really bad about the current model of submitting and rev...
I wanted to write contingency tables in HTML with hwrite(). I realized that the method hwrite() does not exist for the table objects. I could use as.data.frame(), but the table produced is non-intuitive. I did a search on R-bloggers and I quickly found the solution to my problem: the as.data.frame.matrix() function. The contingency table A
This is an edited version of A Direct Marketing In-flight Forecasting System. The original article was written by Shannon Terry and Ben Ogorekm, Nationwide Insurrance, in order to enter the “Applications of R in Business” contest organised by Revolution Analytics. This is the winning entry of the contest. I added some notes in the third
If you are reading this vis-à-vis R-Bloggers, then you know how good R, LaTeX, and Sweave are for generating reports and/or conducting reproducible research. It has been particularly valuable for me in Institutional Research where there are many reports that I need to prepare on a regular basis (some monthly, some quarterly, some annually). However, one issue
Manually combining R code and a presentation can be quite a pain. Luckily, using tools like odfWeave, Sweave and knitr, integrating documents and R code is quite painless. In this post I want to take a look at combining the… See more ›
Code Readability is maybe the most important part of producing reproducible research. If it's impossible (i.e. very costly) for somebody else to read/understand the computer code that underlies your results, then the odds are that they will never be...

I love TikZ in LaTeX and I use it exclusively when writing figures for my papers. I also use the tikzDevice package to convert all figures I create in R to TikZ code, so the font used in the text and figures is the same (and having your R figures in Ti...
I recently discovered knitr for dynamic report generation in R. It seems like a very powerful alternative to Sweave. Particularly, I am interested in png graphic device support (it supports more than 20 graphic devices) and R code formatting.Check it o...
