Greetings R-sig-geo'ders;

I want to use the Pacific-centric world map 'world2' from the maps package
for use with hurricane observations. I am also making use of the sp spatial
data classes. The following (Atlantic-centric) example works:

x = map('world', plot=F)
x_sl = map2SpatialLines(x, proj4string=CRS("+proj=longlat +datum=WGS84"))

However, the map2SpatialLines function when using 'world2' - the
Pacific-centric world map - fails.

x_pac = map('world2', plot=F)
x_pac_sl = map2SpatialLines(x, proj4string=CRS("+proj=longlat
+datum=WGS84"))
*Error in validityMethod(object) :
  Geographical CRS given to non-conformant data*

Interestingly: The range on longitude for x is roughly 0 to 180, while the
range on longitude for x_pac is 0 to 360. Didn't know if that had something
to do with it.

Thanks in advance,
