spectral_spews {spatialwarnings}

(DEFUNCT) Spectrum-based spatial early-warning signals.

Description

Computation of spatial early warning signals based on spectral properties.

Usage

spectral_spews(mat, sdr_low_range = NULL, sdr_high_range = NULL, quiet = FALSE)

Arguments

mat

The input matrix or a list of matrices.

sdr_low_range

The range of values (in proportion) to use for the computation of the spectral density ratio. For example, for the lowest 20 c(0, .2). See also the Details section.

sdr_high_range

The range of values (in proportion) to use for the computation of the spectral density ratio. For example, for the higher 20 c(.8, 1). See also the Details section.

quiet

Do not display some warnings
