sl.view.colbar: View Colourbar

In helgegoessling/spheRlab: Spherical Geometry, Analysis, and Plotting of Geoscientific Data on Arbitrary Grids

Description

View a spheRlab colour bar (by simple plotting).

Usage

sl.view.colbar(colbar, labels = TRUE, labels.cex = 1, labels.col = "black")

Arguments

colbar	a spheRlab colourbar as returned by sl.colbar, that is, a list of length N with characters describing RGB values (hexadecimal) of the colours comprising the colourbar.
labels	a logical value indicating whether or not the colour indices are added as labels.
labels.cex	a scalar that can be used to increase of decrease the label size.
labels.col	the label colour.

Details

This function allows to view a colourbar, independent of how it's applied to a numerical field with corresponding numerical breaks. A simple 'matrix' of the colours is plotted using plot and rect. In contrast to other spheRlab plotting functions, this one is not meant to produce a high-quality figure (in pdf format), but for a quick view.
