There is a great R package written by Thomas Reinholdsson as a wraper for the Booli API (Booli is a Swedish site which hosts data from the real estate market in Sweden)

There are many unexplored areas in the real estate data in Sweden, and this post will attempt to present a few visualizations and ideas.

Before getting started, you have to read and accept Booli’s Terms of Use and then finally register to receive an API key by e-mail.

After this, let’s install the rbooli package:

#check if the package is already installed
 
if(!require(rbooli)){
    devtools::install_github("reinholdsson/rbooli")
