circdensity

From spatstat v1.52-1 by Adrian Baddeley

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

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

x: Numeric vector, containing angular data.
sigma: Smoothing bandwidth, or bandwidth selection rule, passed to density.default.
bw: Alternative to sigma for consistency with other functions.
…: Additional arguments passed to density.default, such as kernel and weights.
weights: Optional numeric vector of weights for the data in x.
unit: 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.

An object of class "density" (produced by density.default) which can be plotted by plot or by rose.

# NOT RUN {
  ang <- runif(1000, max=360)
  rose(circdensity(ang, 12))
# }
