wavevar function

Wavelet variance analysis

Calculates the wavelet variance based on a wavelet multiresolution analysis.

wavevar(f, coord, wavelet = "haar", wtrafo = "dwt")

Arguments

• f: A vector
• coord: A matrix of two columns with corresponding cartesian coordinates. Currently only supports integer coordinates.
• wavelet: Name of wavelet family. haar, d4, and la8. are possible. haar is the default.
• wtrafo: Type of wavelet transform. Either dwt or modwt. dwt is the default.

Returns

Wavelet variance for f.

Examples

data(carlinadata)

coords <- carlinadata[ ,4:5]
pv <- covar.plot(carlina.horrida ~ aridity + land.use,
                 data = carlinadata,
                 coord = coords,
                 wavelet = 'd4',
                 wtrafo = 'modwt',
                 plot = 'var')
