• Optimized the transition() function for 4 and 8 directions with user-defined functions. Run time is reduced by 10+%, and the peak memory consumption is massively reduced.
• Updated deprecated usage of the Matrix library.
• Added unit tests for the transition() function.
• Add workaround (fix?) for pathInc() code in Overview vignette.

gdistance 1.6.2 (2023-04-20)

• Maintainer change

gdistance 1.4

• update the file maungawhau

gdistance 1.3-6 (2020-06-29)

• expanded Description

BUG FIXES

• Fix transition with Mahalanobis distance method use x.minus.y <- raster::getValues(x)[adj[,1],] - raster::getValues(x)[adj[,2],] instead of x.minus.y <- xy[adj[,1],-1]-xy[adj[,2],-1]
