circ_corr {circhelp} | R Documentation |
Computes a circular correlation coefficient as defined in Jammalamadaka & SenGupta (2001).
circ_corr(a, b, ill_defined = FALSE, mu = NULL, na.rm = FALSE)
a |
first variable |
b |
second variable |
ill_defined |
is one of the variables mean is not well-defined (e.g., it is uniformly distributed)? |
mu |
fix the mean parameter of both vectors to a certain value |
na.rm |
a logical value indicating whether NA values should be removed before the computation proceeds |
