This is a package currently under development for Sublime Text 2 that enhances its functionality as an editor for the R language.
Included functionality:
-
Enhanced Send code to R process functionality (from R tools). User can send R commands to an R process from any section of a document that is scoped as R code (
source.r.*). This allows you to send code from files that aren't simply*.Rsource files -- such as R code found within chunks of SWeave and knitr documents, for example.The selection can span several chunks (across "normal text" blocks) and only the R chunks within the selection are parsed and sent.
-
Adds syntax file to support editing Rmarkdown (
⌘⇧P Set Syntax: Rmarkdown).
Add a rule to your favorite color scheme to set the background of R chunks to a slightly different color in order to make them easier to recognize. For example, to set the background color of embedded R source code to be a dark grey, you would:
...
<key>settings</key>
<array>
...
<dict>
<key>name</key>
<string>Embedded R</string>
<key>scope</key>
<string>source.r.embedded</string>
<key>settings</key>
<dict>
<key>background</key>
<string>#1B1B1B</string>
</dict>
</dict>
</array>
...
A modified copy of Monokai Soda that includes such a highlight rule is included in this package.
The impetus to develop this package was to support authoring Rmarkdown files in something besides Rstudio. While Rstudio is a great project, its editor was too slow to work in for me on my machine, which left me pining for something a bit less painful. I have been using Emacs/ESS for the longest time, but I know Python much better than elisp, and I've always felt a bit more at home with TextMate-like editors.
The initial functionality for sending commands to a running R process was forked from the excellent R tools package.
