In ballengerj/FishyR: Functions to Facilitate Standard Analyses Conducted in Fisheries Science

Calculate variogram summary statistics and plots

Description

Variogram_Plot is a wrapper funtion that allows the efficient computation of numerous variagram statistics and variogram plots over a range of considered "plausible" distances.

Usage

Variogram_Plot(
  data,
  mindist,
  maxdist,
  length,
  type,
  map = FALSE,
  cloud = FALSE,
  bins = 100
)

Arguments

data	numeric data frame with two columns. First column should represent the "x"-coordinates and the 2nd column represents the "y"-coordinates. These columns must be titled "X" and "Y", respectively
mindist	numeric value representing the minimum distance over which variogram statistics should be calculated
maxdist	numeric value representing the maximum distance over which variogram statistics should be calculated
length	numeric value representing how many points between mindist and maxdist variogram statistics should be calculated
type	logical; if TRUE, use Cressie's robust variogram estimate; if FALSE use the classical method of moments variogram estimate. See variogram
map	logical; See variogram
cloud	logical; See variogram
bins	numeric value used to calculate the width (See variogram) of subsequent distance intervals

Value

Data frame with results statistics and a series of variogram plots at different threshold distances
