[R] How to avoid copy-paste when copying code from this list

[baptiste auguie]

Neat!

What if, instead, one wanted to format his/her code in the console
before sending it by email? Any tips for that?

(I proposed something like options("prompt"=" ") above, but got stuck
with adding a comment # to printed results)

Thanks,

baptiste
