Dear R - Mapping specialists,
for a prospective publication on using date/times etc in R,
we are looking for a way to draw a world map additionally with
the "timezone stripes".
Thanks to Roger Bivand, it was easy to get to the world map:
I've used this
and later also found
Note that I'm pretty much an ignorant of the diverse shapefile
and other GIS data formats,
[ Furthermore, I'd ideally get a solution (or an *.rda file)
that does not need the 'rgdal' package since that is very hard
for me to get working on our departmental computer, notably the
64-bit ones (problems in installing libgdal / proj.4 / ...).
As it *is* working on some versions of R on some ubuntu servers,
I could use it if needed. ]
Thank you very much in advance!
