Generates pseudo-random numbers from a wrapped normal distribution.
rwrpnorm(n, mu, rho, sd=1)number of random variables to generate.
mean direction in radians of the wrapped normal distribution.
concentration parameter. rho must be between 0 and 1.
different way of select rho, see details below.
Returns a vector of n independent random variables generated from a wrapped normal distribution.
n random variables are generated from a normal distribution with mean
direction mu, and variance -2*log(rho). The function returns these
values modulo 2*pi. You can set rho by using sd with the following equivalence:
$$
\rho = \exp{- \sigma^2/2}
