Performs a Rayleigh test of uniformity, assessing the significance of
the mean resultant length. The alternative hypothesis is a unimodal
distribution with unknown mean direction and unknown mean resultant
length if mu
is NULL
otherwise the alternative hypothesis is a unimodal distribution with a specified mean direction and unknown mean resultant length.

Returns a list with three components: the mean resultant length, statistic
, the p-value of the test statistic, p.value
and
the value of the alternative mean direction mu
