simmatrixMaker | R Documentation |
Legacy function that runs on raster::stack. Applies pairwise comparisons of Schoener's D-metric between each RasterLayer in a RasterStack to populate a similarity matrix.
simmatrixMaker(assignmentRasters, nClusters = FALSE, csvSavePath = FALSE)
assignmentRasters |
Input RasterStack |
nClusters |
Clusters to create run in parallel using 'doParallel'. Defaults to FALSE. |
csvSavePath |
Optional savepath to write similarity matrix to csv file. Defaults to FALSE, will not create csv. |
# Create probability-of-origin maps to compare.
