Hi Petr,
Thank you for pointing that out! Silly newbie here.
So, just want to make sure my mind,
using my example:
par(mar=c(2, 6, 5, 4))
m<-map('world', xlim = c(91, 142), ylim = c(25, 40),
lwd=1.5, col = "grey",border=NA, fill = T, bg="white")
box()
first, map use the first mar=c(2,6,5,4),
and then defines the new mar that is mar=c(4.1, 4.1, par("mar")[3],
0.1)=c(4.1, 4.1, 5, 0.1).
And then box using the new mar=c(4.1, 4.1, 5, 0.1). Is that right?
I am sorry if out of topic. Maybe further I will post at r-sig-geo. Thank you.
