Progress on the ggplot2 user interface is coming along. Please check out this VLOG which will give a good idea of where I currently am in the process. http://neolab.stat.ucla.edu/cranstats/vlog2.mov As always comments and suggestions are welcome. If you would like to try it out yourself, you can install the development version of Deducer using install.packages("Deducer",,"http://www.rforge.net",type="source") 
Hadley Wickham has announced that new versions of his popular grammar-of-graphics charting package ggplot2 and his general-purpose data reshaping tool plyr for R are now available. plyr boasts several new features, most notably a new join function which should simplify what can sometimes be a difficult process in R: merging two data sets. A simplified SQL-like terminology should make...
As prolific as the CRAN website is of packages, there are several packages to R that succeeds in standing out for their wide spread use (and quality), Hadley Wickhams ggplot2 and plyr are two such packages. And today (through twitter) Hadley has updates the rest of us with the news: just released new versions of plyr and ggplot2. source...
The R community is unique as programming communities go. Many users of R come from academia and have a relatively extensive mathematical background. The R community has developed in relative isolation from some other areas of programming th...
The LaTeX beamer package can be used to create appealing presentations for many applications. A working knowledge of LaTeX is required but once the initial learning curve and transition is made from a visual word processor to a markup based approach the benefits are worth the initial investment of time. Title Pages In a previous post we
LATITUDE + LONGITUDE + OVERPLOTTING FIX = MAPS Decision Science News is always learning stuff from colleague, physicist, mathlete, and all-around computer whiz Jake Hofman. Today, it was a quick and clean way to make nice maps in R without using any map packages: just plot the latitude and longitude of your data points (e.g.
Peter Huber referred to “the rawness of raw data”, a kind of data we would not expect to find in a textbook. The book of Fahrmeir and Tutz on multivariate modelling refers to the visual impairment data from Liang et al., 1992 in table 3.12: Nothing wrong here at first sight; but how would you
It is fairly straightforward to set the margins of a graph in R by calling the par() function with the mar (for margin!) argument. For example, par(mar=c(5.1,4.1,4.1,2.1) sets the bottom, left, top and right margins respectively of the plot region in number of lines of text. Another way is by specifying the margins in inches
After the recent foray into stock analysis using quantmod, I thought it worthwhile to mention that the library can be used to analyze a wide variety of investments, including precious metals. It is also worthwhile to mention that there are other ...
Ever since I first looked at this NYT visualization by Amanda Cox, I’ve always wanted to reproduce this in R. This is a plot that stacks multiple time series onto one another, with the width of the river/ribbon/hourglass representing the strength at each time. The NYT article used box office revenue as the width of 
Zero Inflated Models and Generalized Linear Mixed Models with R.
