I like the Economist theme in the latticeExtra package. It produces nice looking charts that mimic the design of the weekly newspaper, such as in this example:
For some time I wondered how I could put the title of my lattice plots into the top left corner as well (by default titles are centred). Reviewing the code of the theEconomist.theme function by Felix Andrews reveals the trick. It is the setting of par.
Last week I mentioned the grid.arrange function of the gridExtra package that allows me to combine graphical grid objects onto one page. The latticeExtra package provides another elegant solution for trellis (lattice) plots: the function c.trellis() or just c() combines the panels of multiple trellis objects into one. Here is minimal example from the help file of c.trellis: library(latticeExtra)
In my next example I am using data from Eurostat, the statistical office of the European Union, showing the use of public transport in four countries.
