[R] Color Alaska in USA map

[Ray Brownrigg]

Did you try USA:Alaska?

That should work.  I don't have the latticeExtra package installed so I cannot easily test 
your code, but map("world", c("USA", "Hawaii"), fill=TRUE) looks OK to me.  However you 
don't actually show the code you are using when attempting to colour Alaska.
