Is there an R-extension to Emacs autocomplete-mode that can be used with ESS?
If the extension doesn't exist I'd also appreciate any hints for writing one!
回答1:
There is an ac-source for R here. I recall struggling with it and finally wrote my own which at that time was much faster, but buggy since I didn't manage to make prefix regexp work properly.
EDIT: the newest ESS (only svn currently) has out-of-the-box integration with auto-complete. I have added the instructions to the wiki.
回答2:
auto-complete-acr is auto-complete sources.
it is more useful than ac-R.
add to .emacs below.
(require ‘auto-complete)
(require ‘auto-complete-acr)
