FPDglm_grid: Calculate Grid search functional phylogenetic diversity...

In funphylocom: Functional traits, phylogenies, communities, simulations

Description

Calculate deviances over a grid of the phylogenetic weighting parameter, a, for generalised linear models using functional-phylogenetic diversity indices as predictors.

Usage

FPDglm_grid(tab, y, PDist, FDist, a = seq(0, 1, 0.01), p = 2,
  index = "mpd", abundance.weighted = FALSE, saveGLMs = FALSE, ...)

Arguments

tab	The community by species presence table.
y	An ecosystem function (or other site characteristic being used as a response variable).
PDist	A phylogenetic distance matrix.
FDist	A functional distance matrix.
a	A vector of numbers between 0 and 1 giving the amount of weight to put on PDist relative to FDist. It is best if a is an evenly-spaced grid.
p	A number giving the p-norm.
index	Character string indicating the diversity index used to combine distances and community data. Currently, either 'mpd' or 'rao'.
abundance.weighted	Should mean pairwise distances be weighted by species abundance? (default = FALSE). Only relevant if index = 'mpd' and tab is an abundance matrix.
saveGLMs	Should GLMs for every point along the grid be saved as an attribute, glms?
...	Additional arguments to pass to FPDglm.

Value

TODO.
