Hi all,
I am testing R by trying R on command line (ie without opening R
console) on a Mac Pro with 10.6. So I created a file plot.R:
x11(width=5,height=3.5)
plot(1:10,1:10)
So I have two questions below (please forgive me if the questions have
been asked already)
1. What is the different between *R CMD BATCH infile.R* and *R --vanilla
--slave < infile.R*?
Those are quite similar. A couple of differences are:
--vanilla changes the startup options. You'll use fewer of the profile
etc. files. See ?Startup for the details.
R CMD BATCH sets up an output file to collect the output. It would
likely be called infile.Rout. It would also have a proc.time() call
added at the end.
2. When I ran plot.R with one of the above methods, the plot showed up
for like a second and disappear. What should I do to keep the plot there
until the user closes it?
If you have a user involved, you should be running interactively, not in
batch mode. You can automatically run your infile.R ahead of starting
the session by setting an environment variable named R_PROFILE_USER
pointing to that file; e.g.
R R_PROFILE_USER=infile.R
(which sets the variable temporarily, only for that session).
Thanks,
D.
