Circular correlations between two circular variables.
circ.cors1(theta, phi)The first cirular variable expressed in radians, not degrees.
The other cirular variable. In the case of "circ.cors1" this is a matrix with many circular variables. In either case, the values must be in radians, not degrees.
A matrix with two columns, the correlations and the p-values.
Correlation for circular variables using the cosinus and sinus formula of Jammaladaka and SenGupta (1988).
