Generating sine wave sample — sin

n-1 points are drawn from a normal distribution with mean=0, sd=1, the points in the final direction are calculated as the sine of the values of direction n-1 with additional jittering controled by the jitter factor f.

Usage

sin_data(n, p, f = 1)

Arguments

n: number of sample points to generate
p: sample dimensionality
f: jitter factor, default=1

Value

sample points in tibble format
