RfPhi | R Documentation |
This function applies the RfPhi technique to object data following a Chi squared statistical test for the most uniform distribution of object orientations.
RfPhi(my.par, out.file, section.title, weight.vec = TRUE, unit.area = "px")
my.par |
A data frame object returned by |
out.file |
Path to PDF file where a standardized plot of the sectional results is made. |
section.title |
Title of the sectional analysis. |
weight.vec |
Logical, if TRUE an eccentricity weighting is applied such that more elliptical objects influence the vector mean stronger than objects with more circular shapes. |
unit.area |
The unit of measure in which the mean object area is calculated. If, for example, the input data is returned from |
Function creates a standardized PDF file containing an RfPhi plot, sectional Rs ellipse, Chi square plot, and a list of calculated properties. These properties are also returned via an object of class RFPHI
