Generate an adjacency matrix from Delaunay Triangulation in R I have a dataframe with a list of coordinates (lat, long) as below: point lat long 1 51 31 2 52 31 3 52 30 4 56 28 5 57 29 6 53 32 7 54 35 8 52 32 9 48 30 10 49 27 I already managed to generate the Delaunay triangulation using the code below: library(deldir) vtess <- deldir(df$lat, df$long) plot(vtess, wlines="triang", wpoints="none", number=FALSE, add=TRUE, lty=1) What I would like to do now is to generate an adjacency matrix (10 by 10 matrix) having the following cell values: How did you generate the triangulation? It would be better if we could start from where you are rather than have to figure that out too. – G5W 2 days ago 2 Answers 2 To OP: Please note th...
