[R] bug in map('world') ?

[Joerg van den Hoff]

hi,

did'nt see anything in the archive:

map('world',pro='rectangular',para=0)

yields a strange artifact (horizontal bar) extending over the whole map 
at a certain latitude range (approx 65 deg. north), whereas

map('world',pro='rectangular',para=180)

(which should be the same) does not show the artifact.

the artifact shows up in other projections as well, e.g.

map('world',pro='bonne',para=45)


which seems to show that the problem might be in the data base of the 
map (i.e. polygon definition)??


any ideas?

regards,

joerg
