jointP {assignR}

R Documentation

Joint probability of origin

Description

Joint probability for individuals of common origin (product of probabilities)

Usage

jointP(pdR)

Arguments

pdR	SpatRaster of probability density maps, e.g., as produced by pdRaster. All layers must have common spatial extent and projection.

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)

# joint probability for individuals of common origin
jointP(pp)
