Hi
There was package rimage which could read jpeg file in colours and manipulate
with it. However it is not actively maintained and therefore it does not work
in recent versions of R. I believe that R 2.14.0 is the last version able to
use rimage. It was quite simple and I was tempted to start
Hello!
I'm trying to plot a 3D dataset as a scatter-plot, coding Z-axis values
with point size. I pass the following parameters to plot function:

pch = 16,

In my dataset, max(intensity)/min(intensity) is ~4000. However, visual
points vary in radius
