[Gretl-devel] why "xterm -e R" in preferences?

Hi, I've just noticed that in gretl's preferences/configurations the command to start R is specified as "xterm -e R". This is a self-compiled version under Linux Mint, but I'm relatively sure that I didn't write that command. Actually, on this system xterm isn't even installed. So is this intended? (Of course changing it is not a problem, that's not the question here.) thanks sven
