Plot Single Sevariance Model

Source: R/plot_variogram.R
plot_variogram.Rd

This function uses ggplot2 framework to plot semivariogram object results from fit_variogram.

Usage

plot_variogram(object, length = 99, show_range = TRUE)

Arguments

object

An output from fit_variogram function

length

(integer) the length of sequence used to produced fitted data.

show_range

(logical) whether to display range in the plot

Value

A list with plot and tibble with semivariogram information

##  Run semivariance on Principal Component Axis1
# read data
data("landcover")

vfit  <- fit_variogram(data = landcover, response = "MPC1", coords = NULL)
vplot <- plot_variogram(object = vfit, length = 99, show_range = TRUE)

# plot
 vplot$plot


vfit_pc2  <- fit_variogram(data = landcover, response = "MPC1", coords = NULL)
vplot_pc2  <- plot_variogram(object = vfit_pc2, length = 99, show_range = FALSE)

# plot
