[R] RGtk2 help: Show list of column names from dataset and categorize as factor or numeric

[Harsh]

Hi UseRs,
I recently started working with the RGtk2 library. The documentation
is comprehensive and I've tried learning from the examples in most Gtk
tutorials (which have C code). This is a little problematic, but has
helped quite a bit in getting me started.

I would like to create a GUI for file selection, which then displays
the column names from the selected file, and provides the user with
checkboxes with each column name for the user to select. Two columns
of check boxes (Factor Type, Numeric Type) and one column of names is
what I would like to display.

Moreover, I am planning to create a GUI tool that would have tabs in a
notebook layout, each tab providing a certain functionality, beginning
from basic charting of data, and going on to applying regression
models and such on the data.

This requires extensive knowledge in components that RGtk2 provides
which could be implemented for the task outlined above. I have looked
at the omegahat.org examples, but would like to see examples for such
simple tasks as to how one could create a drop down list of column
names to choose for x axis and another drop down allowing the choice
of y axis, etc.

Having made the choice to use RGtk2, I would  appreciate if users
could share their RGtk experience with me.
