Dar Jim,
late, but it works now perfectly. I made a little function for
autoscaling elevation data.
https://stackoverflow.com/questions/50606797/plot-in-real-units-mm/52696705#52696705The
(paper-)printer typically also autoscales, which needs to be
deactivated.
Example for a plot with scale
How about this:
in2mm<-25.4 # scale factor to convert inches to mm
pdf("test.pdf",width=8.3,height=11.7)
pin<-par("pin")
plot(c(0,pin[1]*in2mm),c(0,pin[2]*in2mm), type="n", xaxs="i", yaxs="i")
lines(c(10,10),c(0,10))
text(11,5,"1 cm", adj=0)
lines(c(0,40),c(20,20))
text(20,24,"4 cm")
Thanks a lot!

Hi Christian,
Well, it almost worked. I suspect that the postscript device adds some
padding to account for the printable area, so with a bit of
experimentation, The following example seems to do what you want. When
I printed the resulting file from the GIMP, the box and diamond were
the correct
Hi Christian,
When I have to do something like this, I usually write it in
Postscript using this:
/def mm 2.8346 mul
that converts a dimension in mm to points (1/72 inch). However, this
won't work in R. It may be possible to set up the device like this:
postscript("myfile.ps",paper="a4")
Dear List,
Is it possible to plot in R in "real" units? I would like to draw a
plot on A4 paper, where 1 plot unit would be a mm in reality. Is
something like that possible? I would also like to be able to scale the
plot in x and y direction.
Background: For a project I would have to draw
