I write about R every weekday at the Revolutions blog: http://blog.revolutionanalytics.com and every month I post a summary of articles from the previous month of particular interest to readers of r-help. In case you missed them, here are some articles related to R from the month of September: http://bit.ly/cuFNat presented a profile of Hadley Wickham, author of many popular R packages including ggplot2 and reshape. http://bit.ly/bS71Ld riffed the design of the new Twitter website into a discussion on calculating the Golden Mean with R. Several readers contributed 1-liners based on the Fibonacci sequence: http://bit.ly/dvpemK . http://bit.ly/bunYJE linked to some elegant code for calculating the Mandelbrot set in R, and a beautiful animation of the results. http://bit.ly/ahIZzo linked to a blog post by JD Long on simulating multivariate random variables using copulas. http://bit.ly/a8mjZm announced a ggplot2 data visualization competition. http://bit.ly/cRKEZs linked to a discussion about the merits of dot charts versus bar charts. http://bit.ly/cavSLB announced the availability of Revolution R Enterprise 4.0, available free to academics. http://bit.ly/aBuFEt posted updated statistics on the growth in R packages, and asked what other languages can learn from R's package system. http://bit.ly/cYujCF noted updates to the plyr and reshape packages, featuring improved performance and parallel processing. http://bit.ly/afhkSt noted that R 2.12 is scheduled for release on October 15. http://bit.ly/bw6ylo announced RevoDeployR, Web Services integration for R included in Revolution R Enterprise.
