graphics with rterm

I would like to use R as the graphical interface for a fortran program I am
writing. Presently my fortran code produces a set of data files then sends
an "rterm ..... <filename.r >out.out" line to my windows system. This causes
rterm to read in the data files, draw plots on my screen in milliseconds
.... and then terminate and disappear, plots and all, forever. It's this
last bit of efficiency that I would like to curb. I would like the graphs to
appear and stay until I'm ready to dismiss them. I would rather not have
rterm produce my plots as metafiles because I would like them to be
immediately visible on the screen - I don't want to have to fiddle around
opening graphics files. 

Any ideas? Is rterm the right thing to be using?

Thanks
