Description

This layer adds support for statistical analysis through ESS.

Features:

• All ESS features
• Additional data viewer for R via ess-R-data-view
• Support for Org-Babel
• Better 'equals' behavior via ess-smart-equals

Install

To use this configuration layer, add it to your ~/.spacemacs. You will need to add ess to the existing dotspacemacs-configuration-layers list in this file.

Key Bindings

Inferior REPL process

Send code to inferior process with these commands:

Key Binding	Description
SPC m c c	send knitr/sweave chunk and keep buffer focused
SPC m c C	send knitr/sweave chunk and switch to REPL in insert mode
SPC m c d	send knitr/sweave chunk and step to next chunk
SPC m c m	mark knitr/sweave chunk around point
SPC m c n	next knitr/sweave chunk
SPC m c N	previous knitr/sweave chunk
SPC m s b	send buffer and keep code buffer focused
SPC m s B	send buffer and switch to REPL in insert mode
SPC m s d	send region or line and step (debug)
SPC m s D	send function or paragraph and step (debug)
SPC m s i	start an inferior REPL process
SPC m s l	send line and keep code buffer focused
SPC m s L	send line and switch to REPL in insert mode
SPC m s r	send region and keep code buffer focused
SPC m s R	send region and switch to REPL in insert mode
SPC m s f	send thing at point (function) and keep code buffer focused
SPC m s F	send thing at point (function) and switch to REPL in insert mode
CTRL+j	next item in REPL history
CTRL+k	previous item in REPL history

Helpers

Helpers for inspecting objects at point are available in R buffers only.

Key Binding	Description
SPC m h d	view data under point using [ess-R-data-view][ess-R-data-view]
SPC m h t	view table using [ess-R-data-view][ess-R-data-view]

Options

To turn off the automatic replacement of underscores by <-, set in your ~/.spacemacs:

  (setq-default dotspacemacs-configuration-layers '((ess :variables
                                                         ess-disable-underscore-assign t)))

Alternatively you may enable ess-smart-equals, which also disables replacement of underscores by <-, and additionally replace the equals sign with <- when appropriate:

  (setq-default dotspacemacs-configuration-layers '((ess :variables
                                                         ess-enable-smart-equals t)))
