plot_pc_matern: Plot PC Matérn priors

In sdmTMB: Spatial and Spatiotemporal SPDE-Based GLMMs with 'TMB'

Plot PC Matérn priors

Description

Plot PC Matérn priors

Usage

plot_pc_matern(
  range_gt,
  sigma_lt,
  range_prob = 0.05,
  sigma_prob = 0.05,
  range_lims = c(range_gt * 0.1, range_gt * 10),
  sigma_lims = c(0, sigma_lt * 2),
  plot = TRUE
)

Arguments

range_gt	A value one expects the spatial or spatiotemporal range is greater than with 1 - range_prob probability.
sigma_lt	A value one expects the spatial or spatiotemporal marginal standard deviation (sigma_O or sigma_E internally) is less than with 1 - sigma_prob probability.
range_prob	Probability. See description for range_gt.
sigma_prob	Probability. See description for sigma_lt.
range_lims	Plot range variable limits.
sigma_lims	Plot sigma variable limits.
plot	Logical controlling whether plot is drawn (defaults to TRUE).

Value

A plot from image(). Invisibly returns the underlying matrix data. The rows are the sigmas. The columns are the ranges. Column and row names are provided.
