von Mises Probability-Probability Plot
Plots the empirical distribution of a data set against the best fitting von Mises distribution function.
pp.plot(x, ref.line=TRUE)
x |
vector of angular measurements in radians. |
ref.line |
logical flag: if TRUE a 45 degree reference line is added to the plot. Default is TRUE. |
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.
NULL
A plot is created on the current graphics device.
