Niche Boundary Exceedance

Niche Boundary Exceedance

Usage

boundary_exceedance(
  psi_future,
  boundary_value,
  scale = c("radial", "potential")
)

Arguments

psi_future

Future squared niche distance.

boundary_value

Empirical boundary of the current climatic niche reference in squared-distance units.

scale

"radial" returns exceedance beyond the niche boundary distance; "potential" returns exceedance in squared-distance units.

Value

Numeric vector.

Examples

psi <- c(0.5, 1, 2)
boundary_exceedance(psi, boundary_value = 1)
