gdistance 1.6.4 (2023-06-19)

  • 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 1.6 (2022-10-10)

gdistance 1.4 (2022-03-8)

  • 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]

gdistance 1.3-1 (2020-02-28)

BUG FIXES

  • export method raster,TransitionLayer-method

gdistance 1.3-0 (2020-02-17)

BUG FIXES

  • Fix R:devel errors in running the examples

  • Class changes to BasicRaster
  • Change from igraph0 to igraph 6

  • Update to the new adjacent method in raster

gdistance 1.1-3 (2012-04-01)

  • Further adapting to naming changes in raster ("x" argument)

  • Improved documentation of definitions of different distance functions
  • Dependency on igraph0 -- to be changed to igraph 0.6 after May 31, 2012
