rwin-resize - Emacs Window Configuration for R or Python Code Editing

This set of functions configures Emacs to have my preferred window setup for working with R or python code. Specifically it implements a window setup as follows:

|---------------|
| R code buffer |
|               |
|               |
|               |
|               |
|               |
|---------------|
| RE-Builder    |
|---------------|
| R process     |
|               |
|---------------|

There is one function in the code, ‘rwin-resize’. Calling it with no prefix argument implements a window configuration where R is in the bottom window. With a prefix argument, calling the function puts the inferior Python process in the bottom window. I bind the function to a key-chord, “jq”.

I use the main window for editing code and sending it to the inferior R or Python process.

RE-Builder is a useful tool in Emacs for building regular expressions.

Devoting a window to the inferior R process is a good way to view the output of code sent to it.

Note that the R/Python window is setup as a ‘side-window’ and thus cannot be split and is dedicated to the inferior R process buffer.
