Hi-
I'm a bit confused on how to rescale the range of longitudes to 0:360 in an
object of class SpatialPolygonsDataFrame created from a shapefile originally
scaled from -180:180.

> library(maptools)
> world.eez<-readShapePoly(fn="C:/.../World_EEZ_v6_1_20110512")
> class(world.eez)
[1] "SpatialPolygonsDataFrame"
attr(,"package")
[1] "sp"
> bbox(world.eez)
         min       max
x -180.00000 180.00000
y  -78.57036  87.02394

All of the data I am plotting on a world map are scaled 0:360 in longitude,
and I want to add the world Exclusive Economic Zones (EEZ) to the map.
Advice on rescaling the longitudes in my SpatialPolygonsDataFrame to 0:360
would be appreciated!  The complexity of sp classes have me scratching my
head at the moment.

Thanks,

Tim
