White noise is a random noise with equal intensities at different frequencies. It is most well-known as what appeared on old televisions when no signal was found.
noise_white( dim, frequency = 0.01, pertubation = "none", pertubation_amplitude = 1 ) gen_white(x, y = NULL, z = NULL, t = NULL, frequency = 1, seed = NULL, ...)
The dimensions (height, width, (and depth, (and time))) of the noise to be generated. The length determines the dimensionality of the noise.
Determines the granularity of the features in the noise.
The pertubation to use. Either
The maximal pertubation distance from the
origin. Ignored if
|x, y, z, t||
Coordinates to get noise value from
The seed to use for the noise. If
noise_white() a matrix if
length(dim) == 2 or an array if
length(dim) >= 3. For
gen_white() a numeric vector matching the length of
