unionP {assignR}R Documentation

Union probability of origin

Description

Probabilities that at least one individual came from each location in the assignment area (union of probabilities)

Usage

unionP(pdR)

Arguments

pdR

SpatRaster of probability density maps, e.g., as produced by pdRaster.

Value

SpatRaster.

Examples

# load hydrogen isotope data for human hair in North America
d = subOrigData(group = "Modern human", mask = naMap, genplot = FALSE)

# rescale from environmental isoscape to tissue isoscape
r = calRaster(d, d2h_lrNA, naMap, genplot = FALSE)

# four unknown-origin examples
id = c("A", "B", "C", "D")
d2H = c(-110, -90, -105, -102)
un = data.frame(id, d2H)

# posterior probabilities
pp = pdRaster(r, un, mask = naMap, genplot = FALSE)

# probability that one or more individuals are from a given location
unionP(pp)
