Hello all,

there are some important news about the module!

First of all, the interface is almost finished. See a screenshot on the
wiki page [0].
The layout includes a notebook with a page for each R package (automap,
gstat and geoR), with the available options. Another layout could be a
chiocebox wht the three packages on the top of Kriging section, that
redraws the section accourding to the user's choice.
Let me know which one do you prefer, feel free also to suggest something
new.

The R-GRASS integration is on its way: autofitting the variogram on a
map obtained from a DEM sample [1] works in the proof of concept.  rpy2
is extremely helpful and does not require much more code than the
original R code. More to come in the next days.

The idea for variogram fitting is to plot the variogram in a new frame
and add some controls like sliders and/or text boxes to fill up with
nugget, sill and range values. This will involve Python graphics, not R,
as the former is more flexible.

Comments, suggestions, critics are welcome!

best regards and happy coding to everyone,

Anne
