angle_deltas {clugenr} | R Documentation |
Get angles between average cluster direction and cluster-supporting lines
Description
Determine the angles between the average cluster direction and the
cluster-supporting lines. These angles are obtained from a wrapped normal
distribution (\(\mu=0\), \(\sigma=\) angle_disp
) with
support in the interval \(\left[-\pi/2,\pi/2\right]\).
Note this is different from the standard wrapped normal distribution, the
support of which is given by the interval
\(\left[-\pi,\pi\right]\).
Usage
angle_deltas(num_clusters, angle_disp)
Arguments
num_clusters |
Number of clusters. |
angle_disp |
Angle dispersion, in radians. |
Value
Angles between the average cluster direction and the cluster-supporting lines, given in radians in the interval \(\left[-\pi/2,\pi/2\right]\)
Note
This function is stochastic. For reproducibility set a PRNG seed with set.seed.
Examples
set.seed(123)
arad <- angle_deltas(4, pi / 8) # Angle dispersion of 22.5 degrees
arad # What angles deltas did we get?
arad * 180 / pi # Show angle deltas in degrees
