FryNormData {RockFab}

Determine normalized Fry points and scale to central void region.

Description

Function takes locations of object centroids and calculates the parameters required to execute an interactive Fry plot. This function also determines a scale parameter that aids in data reduction.

Usage

FryNormData(object.data, pie.step = 5, expansion = 2, section.name)

Arguments

object.data

Data frame object returned from ParEx.

pie.step

Angular distance in degrees as a multiple of 180. This is used to divide the fry plot into n wedge shaped regions of distance pie.step where the closest point to the origin within each wedge is saved and the largest of these values is returned. This provides an estimate of the central void diameter.

expansion

An expansion factor to be multiplied to the central void diameter estimate in order to properly scale Fry plots.

section.name

The name of the sectional analysis.

Value

Returns an object of class FRY.
