DistSeason: Distance in seasonal space

In martindurocher/floodStat: FloodNet Regional Frequency Analysis

Description

Return a square matrix of the distance between points in the seasonal space. It is equivalent Euclidean distance applied to regularity (radius) and timing (angle) as cartesian coordinates.

Usage

DistSeason(x, ...)

Arguments

r, a	Coordinates in the seasonal space: radius 'r' and angle 'a'.
form, x	Formula and dataset providing the coordinates of the seasonal space. Must be of the form 'radius ~ angle'.
w	Scale factor to standardize difference between angles.

Examples

scoord <- data.frame(radius = runif(5), angle = runif(5,0,2*pi))
