Hi all,
I have a graphic device divided in 2 areas for a plot.
Is it possible to add lines or points in the first plot after the last one
have been set, without plotting all the data again ?
See ?par, look at mfg. However, you would probably find screen() easier
to use, and the way you have done this you have lost the coordinate system
for the first plot and would need plot(1, new=T) to reset it.
Example
par(mfrow(2,1))
plot(1)
plot(2)
lines(c(1,2)) # should be visible in the first plot
That's not a valid R command.
Thanks for help.
Greetings
