emacs - 向 ESS/R 用户询问有关 .emacs 文件中 elisp 代码的建议

Question

我相信并不是所有的 R 用户都知道 elisp。如果 ESS 用户可以在此处共享 .emacs 文件中的代码，那就太好了。注释良好的代码将特别有用。希望这能促进R用户对ESS的使用。

Answer 1

对我来说，这个东西非常有用:

;; ESS: Emacs Speaks Statistics
(load "~/elisp/vendor/ess/lisp/ess-site.el") 

;; Use shift-enter to split window & launch R (if not running), execute highlighted
;; region (if R running & area highlighted), or execute current line
;; (and move to next line, skipping comments). Nice. 
;; See http://www.emacswiki.org/emacs/EmacsSpeaksStatistics,
;; FelipeCsaszar. Adapted to spilit vertically instead of
;; horizontally.
