As part of a one-day workshop, I have developped an online tutorial on how to create publication quality graphics using R (from an academic point of view).
The tutorial can be found here
http://teachpress.environmentalinformatics-marburg.de/2013/07/creating-publication-quality-graphs-in-r-7/
As mentioned in the tutorial, feel free to send me any feedback, criticism, general comments or bug reports.
Enjoy,
Tim
Btw, the entire tutorial was created using Rmarkdown and knitr. The .Rmd file can be found here
