A correlation matrix is a table of correlation coefficients for a set of variables used to determine if a relationship exists between the variables. The coefficient indicates both the strength of the relationship as well as the direction (positive vs. Negative correlations). In this post I show you how to calculate and visualize a correlation matrix using R. 9 definitions of P&R. Definition of P&R in Military and Government. What does P&R stand for?

von Mises Probability-Probability Plot

Lot R Parking Pass

Plots the empirical distribution of a data set against the best fitting von Mises distribution function.

Arguments

vector of angular measurements in radians.

R Lot P'p ' Lp O

logical flag: if TRUE a 45 degree reference line is added to the plot. Default is TRUE.

Details

The maximum likelihood estimates of the parameters of the von Mises distribution are computed from the given data set. The empirical distribution function is plotted against a von Mises distribution function with parameters given by the MLEs computed.

Value

NULL

Note

A plot is created on the current graphics device.
