utils: Utility functions for vulnerability analysis

In phytomosaic/vuln: Niche-based Vulnerability of Species and Communities

Description

Various utility functions.

Usage

litetvi(spe, y, ybin, ...)

quantileonly(spe, ybin, na.rm = TRUE, ...)

percentileonly(spe, y, ybin, ...)

describe(x, ...)

mae(xx, yy, stdz = FALSE, na.rm = TRUE, ...)

Arguments

spe	matrix or data.frame, species occurrences or abundances.
y	vector, environmental values matching ybin.
ybin	data.frame, of class bingrid.
...	further arguments passed to other functions.
na.rm	logical, should NAs be removed?
x	vector of values to evaluate in describe.
xx, yy	vectors of values to evaluate in mae
stdz	logical, standardize mae output by range of xx?

Details

Lightweight functions to calculate vulnerability indices (litetvi), specific quantiles (quantileonly), or all percentiles (percentileonly).
