Agenda for the R Study Group 2010
Hopefully, this Study Group will operate more like a workshop. That is, it should be maximally flexible and participatory. It would be most useful if we brought datasets which we care about to work with.
Goals for Data Structure and Manipulation
The first half of the workshop will devoted to structuring, manipulating and aggregating your data. Time spent figuring out how to do these things on your own for the first time constitutes an enormous time suck. I think that improving our abilities in these areas will vastly improve our data analysis efficiency.
- General: Discuss the ideal and most flexible formats for data.
- General: Discuss data collection and storage.
- R: Reshaping Data. (
- R: Manipulating And Subsetting Data.
- R: Data Aggregation. (
- R: Efficient workflows.
Goals for Graphical Display
The second half of the workshop will be devoted to generating appropriate and effective graphics,
focusing especially on using the
- General: Discuss appropriate kinds and designs of graphics.
- R: Designing graphics in
- R: Fine tuning graphics in
