Inspect Levels for Contour Plots of Spectra2D Objects

Description

Given a Spectra2D object, this function will assist in selecting levels for preparing contour and image type plots. Any of the arguments to calcLvls can be used to compute the levels, or you can choose your own by inspection.

Usage

inspectLvls(spectra, which = 1, ...)

Arguments

spectra	An object of S3 class Spectra2D.
which	Integer. The spectrum/spectra to be analyzed. If a vector, the intensities are combined.
...	Arguments to be passed downstream to calcLvls and/or the plot function (e.g. ylim).

Value

A numeric vector giving the levels (invisibly).
