heatmap_wave.local.multiple.cross.correlation {wavemulcor}

Auxiliary routine for heatmaping wave local multiple cross-correlations

Description

Produces heatmaps of wave local multiple cross-correlations.

Usage

heatmap_wave.local.multiple.cross.correlation(Lst, lmax,
     lag.first=FALSE, xaxt="s", ci=NULL, pdf.write=NULL)

Arguments

Lst

A list from wave.local.multiple.cross.regression.

lmax

maximum lag (and lead).

lag.first

if TRUE, it produces lag-lead pages with J+1 wavelet heatmaps each. Otherwise (default) it gives wavelet pages with 2*lmax+1 lag-lead heatmaps each.

xaxt

An optional vector of labels for the "x" axis. Default is 1:n.

ci

value to plot: "center" value of confidence interval (i.e. the estimated cross-correlation), the "lower" bound, or the "upper" bound. Default is "center".

pdf.write

Optional name leader to save files to pdf format. The actual name of the file is either "heat_<pdf.write>_WLMCC_lags.pdf" or, "heat_<pdf.write>_WLMCC_levels.pdf".

Details

The routine produces a set of time series vs. wavelet periods heatmaps of wave local multiple cross-correlations at different lags and leads.

Value

Heat map.
