Usage

conColScheme(spectra, old = levels(as.factor(spectra$colors)),
  new = NULL)

Arguments

spectra

An object of S3 class Spectra whose color scheme is to be changed.

old

A character vector of the old color names; will be searched for and replaced one-for-one by the character vector in new.

new

A character vector of the new (replacement) color schemes.

Details

A grepping process is used. Depending upon the nature of the old color names to be searched for, you might need to add some grep pattern matching strings to the color name.
