Subject: width and length arguments to postscript()
Hi everyone
This must be a FAQ but I can't find it anywhere...
I want a postscript image of a contour() plot, with axes of equal
length. Try
R> postscript(file="~/f.ps")
R> contour(matrix(rnorm(100),10,10))
R> dev.off()
This isn't what I want: the plotting region is, as documented, quarter
of an inch shy of the paper edge and the axes appear to be different
lengths. contour() doesn't take a "asp" argument.
postscript() does have a width and a length argument but I can't make
them work as I want:
R> postscript(file="~/f.ps",width=5,height=5)
R> contour(matrix(rnorm(100),10,10))
R> dev.off()
gives axes of about 96mm by 80mm (on A4 paper).
What do I have to do to get square contour plots on a postscript file?
