Using magic commands outside of Interactive Shell in IPython

问题

Is there a way to use "magic commands" from IPython from an outside file? For example if I have a file, "rcode.py" with the code:

%load_ext rmagic
%R a=c(1,2,3);b=c(2,3,4);print(summary(lm(a~b)))

This gives me a SyntaxError for the first line when I run it using ipython rcode.py in the command line. However when I type these lines straight into the interactive shell with ipython it runs fine. Is this because you only do magic in the interactive shell?

Thanks!

If you name your file with a .ipy extension, ipython will parse it properly. You can simply make a symlink if you want:

$ ln -s rcode.py rcode.ipy
$ ipython rcode.ipy
