Linking R to GIS
Dear All, Has anyone worked with linking R to both ArcView and MapInfo GIS systems? My desire is to capture object selection from GIS and pass to R and to return spatially based statistical model results from R to GIS. If both could simultaneously access the same data file this would be a bonus. My inclination is to put together some routines based on ODBC linking but thought I would seek like

I have the shapefile, I have the coordinates but I'm having a great deal of difficulty bringing the two together. The problem is the various GIS packages for R do not play well with each other. sp, shapefiles, maptools, etc all use different

Unfortunately I found no way to make this work, as I'm unable to create a correct list of class "var.ncdf". ###code piece river=list(mode='var.ncdf', length=nriv)
