Auto complete is good, it can save you times in typing and prevent typo sometimes.
RStudio now supports function arguments in auto complete. ESS’s auto complete is more advance, it supports help page.
We should use ‘ess-use-auto-complete’ to activate auto complete in ESS buffers.
(setq ess-use-auto-complete t)
The effect is quite amazing. Auto-complete extension is needed for ESS, we need to install the auto-complete extension and load it at Emacs startup.
Emacs is a great front-end for most of the command line tools. Although R-Studio is pretty good, I think Emacs/ESS is better. I’ve always used Emacs/ESS to run R, since 2007 on Ubuntu, Windows, and my MacBook Pro. It gives me the same experiences across all platforms. I love the way Emacs formatting source codes, and literate programming with Roxygen supported. Unfortunately, ESS does not suport displaying plots in Emacs buffer, which has been supported by imaxima.
