Computes a kernel smoothed estimate of the probability density for angular data.

circdensity(x, sigma = "nrd0", ..., bw = NULL, weights=NULL, unit = c("degree", "radian"))

An object of class "density" (produced by

"density"

density.default) which can be plotted by plot or by rose.

density.default

plot

rose

Numeric vector, containing angular data.

Smoothing bandwidth, or bandwidth selection rule, passed to density.default.

Alternative to sigma for consistency with other functions.

sigma

Additional arguments passed to density.default, such as kernel and weights.

kernel

weights

Optional numeric vector of weights for the data in x.

x

The unit of angle in which x is expressed.

The angular values x are smoothed using (by default) the wrapped Gaussian kernel with standard deviation sigma.
