## What does this package look like?

May 1, 2012
By

In this post, I give a very simple trick to understand the way a package is organized, which functions are included in and how these functions depend from each others. The idea has been brought by one of my student, Soraya, who is currently working in a very hostile environment, surrounded by true geeks. However,

## Gini index and Lorenz curve with R

February 23, 2012

You can do anything pretty easily with R, for instance, calculate concentration indexes such as the Gini index or display the Lorenz curve (dedicated to my students). Although I did not explain it during my lectures, calculating a Gini index or displaying the Lorenz curve can be done very easily with R. All you have

I created an R package to read grads data. As far as I know, there is no dedicated package to read grads data. The package is still quite new, any remarks on the documentation or code are more than welcome.… See more ›

## Creating an R package, using developer/productivity tools

Couple of R programming (mainly infrastructure/workflow) related topics discussed at the Los Angeles R users group in a tutorial/demo-like form (targeted mainly to beginners) by Szilard Pafka and Jeroen Ooms: how easy it is to create a simple package for … Continue reading →

## The fun Package: Use R for Fun!

August 16, 2011

A couple of days ago we released a package named fun to CRAN, but I did not dare to send an announcement to [email protected] as usual. This package is a collection of some classical computer games (e.g. the Mine sweeper and Five in a row) as well as other funny stuff. Some examples: ## install.packages('fun')

$Arrogance sampling$

A new posting on arXiv by Benedict Escoto on a simulation method for approximating normalising constants (i.e. evidence) with an eye-catching name! Here is the abstract This paper describes a method for estimating the marginal likelihood or Bayes factors of Bayesian models using non-parametric importance sampling (“arrogance sampling”). This method can also be used to

## formatR update (0.1-6)

January 6, 2011

A new version of the formatR package is available on CRAN now (binary packages are still on the way). There are three major updates: the inline comments will also be preserved in most cases (in earlier versions, only single lines of comments are preserved) tidy.source() gained a new argument 'text' to accept a character vector

## formatR update (0.1-5)

he formatR package has been silent for quite a few months now. Recently I’ve been moving my old packages from R-Forge to GitHub, and I finally killed several things on my TODO list. In the past, I made an awkward decision to let formatR depend on the animation package, which was ridiculous. Ronggui suggested me

## Rd2roxygen: Convert Rd to roxygen documentation

December 1, 2010
By

must admit that I have been tired of maintaining my R packages for a long time, and the main reason is I feel really uncomfortable with writing R documentations (Rd). The required structure of an R package mainly includes two directories R and man — the former for the R source code (typically functions), and
