Every time you are creating plots you might get this error - "Error in plot.new() : figure margins too large
". To avoid such errors you can first check par("mar")
output. You should be getting:
[1] 5.1 4.1 4.1 2.1
To change that write:
par(mar=c(1,1,1,1))
This should rectify the error. Or else you can change the values accordingly.
Hope this works for you.
