+[`adespatial`](https://sdray.github.io/adespatial/) (Dray _et al._ 2023), 
+[`spdep`](https://r-spatial.github.io/spdep/) (Bivand & Wong 2018), 
+[`igraph`](https://r.igraph.org/) (Csardi & Nepusz 2006), 
+[`sf`](https://r-spatial.github.io/sf/) (Pebesma 2018), and 
+[`ggplot2`](https://ggplot2.tidyverse.org) (Wickham 2016).
