In cjcampbell/IsoModAT: Isotope Origin Clustering and Assignment Tools

Generates similarity matrix for SpatRaster objects in environment.

Description

Usage

schoenersDsimmatrix(spatrast)

Arguments

spatrast

Input SpatRaster

Examples

# Create probability-of-origin maps to compare.
myiso <- rast(isoscape, type="xyz")
plot(myiso)
myiso_sd <- rast(isoscape_sd, type="xyz")
n <- 5
set.seed(42)
df <- data.frame(
         ID = LETTERS[1:n],
         isotopeValue = sample(-120:-40, n),
         SD_indv = rep(5, n)
         )

                        ID = df$ID,
