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 png(file="master.png") plot(1:10) ## Save a copy on png dev 3 png(file="copy1.png") dev.set(2) dev.copy(which=3) ## Add details to copy, write to disk and view abline(v=5) 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?
