This is a release to ensure as much functionality as possible for the Binder.org container. There is no functional difference between v1.1.1, v1.1.3, and this version v1.1.5. All these subpoint releases are a tortured attempt at getting the Binder container to work. If you do not have the compute structure to download this repository and then run the code on your own local computer, you may want to try the Binder option by launching the RStudio container < https://mybinder.org/v2/gh/libjohn/mapping-with-R/master?urlpath=rstudio >. However, I think the best results will be found by downloading the repository and running the code on your own compute using the free and open source tools [R, Tidyverse, other R packages].
