是否有可能获得对R在Emacs ESS code完成类似于在Rstudio可用？ [英] Is it possible to get code completion for R in Emacs ESS similar to what is available in Rstudio?

问题描述

Rstudio有一个伟大的code完成功能。它提供了与给定字符串开头的功能，以及功能和参数定义的快速视图。

Rstudio has a great code completion feature. It provides a quick view of functions that start with a given string, as well as function and parameter definitions.

ESS是足够强大，我熟悉的，并集成到Emacs的，在这里我进行我的大部分工作 - 所以我不敢随便移动，但该功能是让我考虑这种做法。

ESS is powerful enough, familiar to me, and integrated into Emacs, where I conduct most of my work - so I am hesitant to move, but this feature is making me consider such a move.

是否有可能整合这个功能到Emacs ESS？

任何希望，将有（如果有的话，我怎么可能支持这种努力？）

Any hope that there will be (and if so, how could I support such an effort?)

lm(

和命中TAB一个新的缓冲区中打开它得到我上面的窗口的左侧：可用的选项手头的功能。我不认为你可以显示直接的帮助，虽然。

有/也是一个办法打字，但我已经forgottten如何/在哪里的导通。当获得在小缓冲区上下文相关帮助

There is / was also a way to get context-sensitive help in the mini-buffer when typing but I have forgottten how/where that gets turned on.
