Calling Nim from R

A super short introduction how to call Nim code from R using the .C interface. I’m not an R user normally, so I googled and used this post as a reference: https://www.r-bloggers.com/three-ways-to-call-cc-from-r/

Let’s define a simple procedure, which we want Nim to do:

The official installation guide (https://wiki.archlinux.org/index.php/Installation_Guide) contains a more verbose description.

This snippet makes Vim automatically continue/end lists in insert mode, similar to the way word processors do:

It automatically adds the bullet/number for the next list item when you press Return at the end of an existing item,
When you press Return on an empty list item, it removes the bullet/number, ending the list.

It supports ordered lists with markers like 1. and unordered lists with - markers (because those are the markers I use.)

(It's particularly useful when using an iOS keyboard where punctuation and numerals are slow to access.)

	library(ggmaps) # for fortifying shapefiles

	# First read in the shapefile, using the path to the shapefile and the shapefile name minus the
	# extension as arguments
	shapefile <- readOGR("path/to/shapefile/", "name_of_shapefile")

	# Next the shapefile has to be converted to a dataframe for use in ggplot2
	shapefile_df <- fortify(shapefile)
