An index of my R packages, with links to documentation, source code, and publications or examples.
Inspired by some questionable published science, this post shows how much you can influence the correlation by cherry-picking outliers and removing them.
A light-weight implementation of confidence intervals for fitted linear-mixed effects models, by applying the semi-parametric bootstrap provided by bootMer.
Four examples on plotting colored geographic maps in R. This simple example is for Australian population by state, but applies to more complicated datasets also.
An early implementation of an R package with a few utility functions for non-linear regression, including nls, loess, nlme, quantreg. It is particularly easy to plot fitted models, and compare coefficients between models.
Several working examples on reading, reshaping, and cleaning data from a variety of Web sources, including text, HTML tables, Excel spreadsheets.
