Scatterplot with marginal boxplots

Using R and ggplot2 to draw a scatterplot with the two marginal boxplotsDrawing a scatterplot with the marginal boxplots (or marginal histograms or marginal density plots) has always been a bit tricky (well for me anyway).

InstallOldPackages: a repmis command for installing old R package versions

February 3, 2013
By

A big problem in reproducible research is that software changes. The code you used to do a piece of research may depend on a specific version of software that has since been changed. This is an annoying problem in R because install.packages only installs the most recent version of a package. It can be tedious to collect the old...

Somehow, simple results because more complicated to compute just because we have to take into account...
