.interpCoordFromQuantile: Latitude of quantile(s) of the geographic abundance distribution

Description

This function returns the latitude or longitude of quantile(s) of the geographic abundance distribution. The input is derived from a rasterized map of the species abundance distribution. If a quantile would occur somewhere between two cells, the latitude/longitude is linearly interpolated between the cells bracketing its value.

Usage

.interpCoordFromQuantile(
  latOrLong,
  quants,
  x,
  coordVect,
  weightedElev = NULL,
  warn = TRUE
)

Arguments

latOrLong

Either 'latitude' or 'longitude'

quants

Quantile value(s) (i.e., in the range [0, 1])

x

Matrix of abundances.

coordVect

Vector of latitudes, one per row in x (from south to north!!!) **OR** vector or longitudes, one per column in x (from west to east!!!).

weightedElev

Raster of elevations weighted by x1 or x2 or NULL.

warn

Logical. Show warnings.
