checkNormality: Check visualy of the normality of the sample

In AFM: Atomic Force Microscope Image Analysis

Description

checkNormality performs a visual check to know if the distribution of heights of an AFMImage follows a normal distribution. The function displays Quantile/Quantile and distribution plots.

Usage

checkNormality(..., AFMImage)

Arguments

...	pngfullfilename (optional): directory and filename to save the visual check to png or pdffullfilename(optional): directory and filename to save the visual check to pdf
AFMImage	an AFMImage from Atomic Force Microscopy
