Over the past weeks I have tried to replicate the figures in Lattice: Multivariate Data Visualization with R using Hadley Wickham’s ggplot2.
With the exception of a few graph types (e.g. ggplot2 doesn’t support 3d-graphs, and there were a few other cases), it was possible to create ggplot2 versions of almost all the figures. Sometimes this 
This post is a summary of my two previous posts on the trend analysis with the Cox-Stuart test and on simple linear regression. The goal that we propose is to assess the trend in the number of visits received from a site over a long time. I use Google Analytics, because this tool allows us to save...

I have just reviewed the book Applied Spatial Data Analysis with R which has been published in the September2009 issue of the Royal Statistical Society’s Significance magazine. Applied Spatial Data Analysis with R is an accessible text that demonstrates and explains the handling of spatial data using the R Software Platform. The text’s authors have

Additional functionality in R is added through packages, which consist of libraries of bundled functions, datasets, examples and help files that can be downloaded from CRAN (the Comprehensive R Archive Network). The function install.packages() or the w...
“Since 1751 approximately 329 billion tons of carbon have been released to the atmosphere from the consumption of fossil fuels and cement production. Half of these emissions have occurred since the mid 1970s. The 2006 global fossil-fuel carbon emission estimate, 8230 million metric tons of carbon, represents an all-time high and a 3.2% increase 
Ever since I began using R about ten years ago, the best place to find R help was on the R-help mailing list. But it is time-consuming searching through the archives trying to find something from a long time ago, and there is no way to sort out the good advice from the bad advice.
