inspectLvls: Inspect Levels for Contour Plots of Spectra2D Objects
In ChemoSpec2D: Exploratory Chemometrics for 2D Spectroscopy

Description Usage Arguments Value Author(s) See Also Examples

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.

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

`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`).

A numeric vector giving the levels (invisibly).
