The goal of tilegramsR package is to provide R spatial objects in sf (Pebesma 2016) format representing various Tilegrams. The primary purpose of this data is to be used for data visualization. The objects provided can be plotted using base R plotting, ggplot2 (Wickham 2016), or leaflet (Cheng, Karambelkar, and Xie 2017).

To know more about Tilegrams see this post and a this web app.
