Hi Brett,
To anyone who is interested, I'm trying to learn a bit more about developing applications in R with user interfaces. I've been playing around with gWidgets to develop a model building interface. I'd appreciate any comments, suggestions, or guidance on how to better structure my R code and organize the programming task. In addition, any suggestions for features and improvement to this fledgling project would be welcomed.
I found the proto package to be most useful in structuring the code while developing my R2STATS interface for GLM and GLMM. Proto uses a prototype approach, as you would infer from the name, but can be used in an object-oriented approach as well.
