I have a graph (a curve with a x- and y-axis) on paper. (The device from
which I receive this is not able to output the data digitally
unfortunately.) Is there a procedure by which I can scan the graph, save it
into, e.g., a bitmap file and make it R to read this file into x and y
coordinates?
Thanks, Aad Termorshuizen
