Plot standardized pairwise correlation or covariance for Matern family

Source: R/matern_helpers.R
plot.std_matern_corr.Rd

Visualization method for std_matern_corr objects using ggplot2. It can display the Pairwise Correlation Function (PCF) for LGCP models or the standard Matern covariance function.

Usage

# S3 method for class 'std_matern_corr'
plot(x, type = c("pair.cor", "covariance"), scaled = FALSE, ...)

Arguments

x

An object of class std_matern_corr.

type

Character string. Either "pair.cor" (default for LGCP) or "covariance".

scaled

Logical. If TRUE, uses the min-max scaled PCF (pair_cor_sc) or the standardized covariance (\(C(r)/\sigma^2\)). Default is FALSE.

...

Additional arguments (currently ignored).

Value

A ggplot object.

Examples

if (FALSE) { # \dontrun{
# Assuming 'cov_lgcp' is an object returned by std_matern_corr()
plot(cov_lgcp, type = "pair.cor", scaled = TRUE)

# To modify the plot
library(ggplot2)
p <- plot(cov_lgcp, type = "covariance")
p + theme_bw() + ggtitle("Spatial Decay")
} # }
