* Description
This layer adds support for statistical programming languages to Spacemacs.
** Features:
- Syntax highlighting
- Auto-completion
- Syntax-checking via [[https://github.com/jimhester/lintr][lintr]]
- Additional data viewer for R via [[https://github.com/myuhe/ess-R-data-view.el][ess-R-data-view]]
- Support for Org-Babel
- Showing of inline help for =R= constructs
- Repl support via =R terminal=
- Support for =S=, =SAS= and =R=
- Much more via the [[https://ess.r-project.org/Manual/ess.html#Current-Features][ESS Project]]
* 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.
Also install [[https://github.com/jimhester/lintr][lintr]] library via the R terminal to enable syntax checking.
To do so start the R terminal and type below code.
#+BEGIN_SRC R
install.packages("lintr")
#+END_SRC
* Options
Use a key binding to insert =<-=:
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-configuration-layers '((ess :variables
ess-assign-key "\M--")))
#+END_SRC
* Key bindings
