artyfarty focuses on providing easy access to a few ‘nice’ ggplot theme, it also includes a number of predefined palettes and watermark convenience functions.
artyfarty is a work in progress. For now you can install the development version using devtools.

A number of palettes are available through the pal() function. A visual overview can be acquired as follows:

Check out the examples above to see how these palettes can be applied, refer to the ?pal() documentation for more details
A watermark might not add much value to a plot, but there are times that you just need to be able to to add a simple watermark.
