map projections
I don't know of any R code for this, but there is a freely available software package from the US Geological Survey supporting over 70 different projections, including the ones you mention. You can get it from ftp://kai.er.usgs.gov/pub/Proj.4/ The relevant file is PROJ.4.3.3.tar.gz. The documentation is very good (get the the postscript files PROJ.4.3.ps.gz, OF90-284.ps.gz, and SWISS.ps.gz from the above directory). I know NetBSD has this in the Packages Collection http://www.netbsd.org/packages/misc/proj/ (I ought to know, I imported it). I think Debian GNU/Linux has it also. So if you use one of these systems you might not need to compile it yourself. Regards, Jason Beegan.
G' Day, Can you please tell me if there is R code for geographic projections? ie lat, lon -> x,y metres. I'm principally interested in Mercator and Lambert Equal Ar ea Azimuthal. Failing R code - code in any language!
