One of my dear readers, C S, has pointed out to me the R package latticist. In the beginning I was sceptical, since the package is merely more than an interface to existing visualization routines. However, I now consider it astonishingly useful and use it almost every day. The reason is simple: Getting an intial glimpse onto a large set of multivariate data is tedious in R, due to the command line interface. With latticist, you get an instant overview over all variables of interest and it allows you to quickly dive into details by selecting subgroups and to look at potential correlations. Recommended.
