First, I want to say thank you to all who answered and offered help, especially to them I haven't answered yet.
We have a plan now. The next meeting will be on January, 16th. Time and location will be announced soon, but probably it will take place around 6pm in the IMISE. And the meetup will be focused on graphics. Therefore we want to collect questions, problems around R Graphics and hopefully present the solutions.
So if you have seen a graph and you do not know how to produce it, or you do not know how to get the legend in the right place, create a axis break in lattice, combine several graphs, etc pp, please write an email. If you have a favorite graphics package (the *traditional*, lattice, ggplot2), please add this information. Besides we want to present some ways of interactive data exploration in R.
There will be another session about importing and exporting data to and from R. So questions about this topic are also welcome (as well as any other questions).
Hope to see many of you next year. Have a stressless Advent, a nice Christmas and a healthy New Year.
