Roger Thank you for your quick and helpful response.
I now have image/plot() working. I need some help in how to go from rectangular grid representation to a mercator (or other) projection. Since my source grid is 2 degree long/lat based, I'd like to use a projection. How do I get a proper projection? Here's the line I used: gr_sp <- SpatialGrid(grid=grd, proj4string = CRS(as.character(NA))) Sorry for such a basic question. -- View this message in context: http://r-sig-geo.2731867.n2.nabble.com/SpatialGridDataFrame-Help-tp5463824p5465477.html Sent from the R-sig-geo mailing list archive at Nabble.com. _______________________________________________ R-sig-Geo mailing list R-sig-Geo@stat.math.ethz.ch https://stat.ethz.ch/mailman/listinfo/r-sig-geo
