I offer several courses at various levels of R, ranging from 1 to 3 days and from introductory to advanced topics.
It is often offered through the Columbia Mountain Institute of Applied Ecology (http://www.cmiae.org).
A sample offering is found at http://cmiae.org/event/advanced-r-programming/
I can also do this or other courses onsite at your organization. Please contact me (Carl Schwarz) for information.
All slides from all levels of this course are available in this directory.
