I think in the end this would
require an ogr/gdal driver for sp objects as Barry Rowlingson has
previously suggested here, and in the r-sig-geo lists.
Progress on this has been minimal: I managed to create an ogr driver
with a new name! There's a few places that you need to edit to link in
the new driver in the ogr build system. Then I started to worry about
how to link in to libR.so and stopped there. I need to find out how the
OGR build system works with other library dependencies, and that
probably means understanding autoconf... Beyond me at the moment...
I have started to look at some brushing and linking functions using the
iPlots R package, and should hopefully be able to implement some of
these things in the future...?
Isn't the ultimate in linking and brushing GGobi? There's a link from
R to GGobi for displaying R data in GGobi. What might be nice would be a
GGobi plugin for Qgis - set up so that brushed items in the GGobi view
are highlighted in the Qgis map.
I've looked at the C code in the R-GGobi interface and it looks very
difficult....
