evaluateVariogramModels: evaluateVariogramModels method to evaluate the basic variogram models

Description

evaluateVariogramModels method to evaluate the basic variogram models available in the gstat package A AFMImageVariogramAnalysis method to handle the variogram analysis of an AFMImage. The variogram models used can be seen with the show.vgms() function from the gstat package.

Usage

evaluateVariogramModels(AFMImageVariogramAnalysis, AFMImage)


  ## S3 method for class 'AFMImageVariogramAnalysis':
evaluateVariogramModels(AFMImageVariogramAnalysis,
  AFMImage)

Arguments

AFMImageVariogramAnalysis

an object

AFMImage

an AFMImage

Examples

library(AFM)

data("AFMImageOfRegularPeaks")
# take an extract of the image to fasten the calculation
AFMImage<-extractAFMImage(AFMImageOfRegularPeaks, 40, 40, 32)
# e.g. AFMImage@fullfilename<-"/users/ubuntu/AFMImageOfRegularPeaks-extract.txt"
AFMImage@fullfilename<-paste(tempdir(), "AFMImageOfRegularPeaks-extract.txt", sep="/")
