Before plotting the map, change the par()$fg to the line colour I want to use for the block, and change it back immediately after the map function is used. Seems to be because of how polygon works. Not very elegant, but it's simple enough to do. -- Patrick Connolly HortResearch Mt Albert Auckland New Zealand Ph: +64-9 815 4200 x 7188 ~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~ I have the world`s largest collection of seashells.

Patrick,
if you look at the code for map, you will see that it uses a
call to polygon if FILL=TRUE: ie
if (fill)
polygon(coord, col = color, ...)
else lines(coord, col = color, type = type, ...)
You can supply extra arguments to polygon when you call map, eg:
map("nz","North.Island",fill=T,col="Wheat",border=0)
see help(polygon) for info on setting borders.

Subject: [R] How do we omit the coastline using map?
I've been able to do most things I'd like to using the map package,
but I can't figure out how to fill a region without drawing a black
outline. I can draw the outline in a specified colour, but as soon as
I set fill to TRUE, I get a black outline in addition.
My map has a lot of activity on the coastline so I don't want a black
line obscuring what I do there. A pale colour to indicate land mass
is what I want to do.
