Mango Solutions is pleased to announce that we will be running an Introduction to R course in Bath on the 24th and 25th June; there are currently a couple of places still available on this course for anyone interested in learning about R, the programming language <http://en.wikipedia.org/wiki/Programming_language> and software environment for statistical <http://en.wikipedia.org/wiki/Statistics> computing and graphics.
The course fee is £900 for commercial participants and £500 for academic participants which covers comprehensive training manuals, tip sheets, USBs and 3 months of free consultative support.
Nb. Should your organization have 3 or more interested attendees we would be pleased to talk to you about running a customized and focused course delivered at your own premises using your own datasets.
A brief overview of the course contents follows. For more information on the course, or to register, please contact [log in to unmask] <[log in to unmask]" target="_blank">http:[log in to unmask]>
