[R-sig-Geo] point and click visualization of data

[Virgilio Gomez Rubio]

Hi,

I am not sure about what you need, bu you may want to try Mondrian for
this:

http://rosuda.org/mondrian/

If you have your data in R (as a SpatialPolygonsDataFrame), you can use
sp2Mondrian to export to a file that Mondrian can read. This will let
you visualize multivariate data very easily.

There is also a plug-in for Quantum GIS called manageR that will let you
import your data into QGIS and point and click very easily.

Hope this helps.

Virgilio
