Using Faceting in ggplot2 to create Trellis-like Plots
One of the main strengths of the Trellis graphics paradigm is the use of panelling to divide data into subsets to investigate whether patterns are consistent as the conditioning variables change. In the ggplot2 package the terminology for specifying these separate panels is faceting and can be used to create similar displays. In our previous post
QQ plots of p-values in R using ggplot2
Way back will wrote on this topic. See his previous post for Stata code for doing this. Unfortunately the R package that was used to create QQ-plots here has been removed from CRAN, so I wrote my own using ggplot2 and some code I received from Daniel Shriner at NHGRI. Of course you can use R's built-in qqplot() function, but...
MATLAB style stem plot with R
Recently I wanted to plot an impulse response function with R and missed the MATLAB style stem plot for doing it. I couldn’t find an R function for it with a quick Google search so I made my own. So here is the function and a small example : #T...

Version 0.6.7 of the Rcpp package---a set of C++ classes making it easier to glue C/C++ code to R---is now on CRAN and Debian. This is a fairly incremental release that contains just a few small changes that arose since the previous release in August.
One change is that a new type RcppList was added which allows us
