This function applies the RfPhi technique to object data following a Chi squared statistical test for the most uniform distribution of object orientations.

`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`
