Hi all, I was wondering if anyone knows how the default orientations are calculated in the mapproj package. I need this for my ggplot2 package because when you are drawing maps with multiple layers of data you (obviously) have to calculate the orientation over all data, not just the data points in a single layer. You can see some of the problems I'm having at http://had.co.nz/ggplot2/coord_map.html
I tried emailing the maintainer of the mapproj package but didn't get a reply. Hadley -- http://had.co.nz/ _______________________________________________ R-sig-Geo mailing list [email protected] https://stat.ethz.ch/mailman/listinfo/r-sig-geo
