I'm working over an ssh connection without X11 graphics. I'm making a
plot, the first stage of drawing which takes a long time. I want to
experiment with adding details. Here is what I was hoping to do, which
results in error.
## Draw the master plot on png dev 2
## Save a copy on png dev 3
## Add details to copy, write to disk and view
Error in int_abline(a = a, b = b, h = h, v = v, untf = untf, ...) :
plot.new has not been called yet
Can someone tell me how to do this correctly?
Thanks a lot,
