[vslist] good plotting program?--MATLAB?

I half agree with Denis. You can do nice graphs in Matlab (even
version 5) but the access to the bells and whistles is a bit
clunky (although as of version 6 there is a GUI interface that simplifies
things). A problem with MATLAB is that the size of symbols
and labels is not necessarily indicative of what you will see
in hardcopy, although you can develop rules of thumb. There
is some freeware on the MATLAB exchange site (exportgraphic.m,
I think, and associated programs) that goes some way to giving
the user better control of this, but it's still a bit clunky.
Gnuplot is quite good but I've never take the time to master its
syntax. What I like about R (and you could do this with
MATLAB, too, but it is a route that I less often pursued)
is that I can put the graphic generating code in a script that
I can tweak and run each time I want to modify the image. Emacs
has a nice interface with R (ESS or Emacs speaks S) that colorizes
the commands but nearly any text editor will work.
The issue may come down to whether you prefer to modify things
by point and click or by programming a script.
