LofC {ChemoSpec2D}  R Documentation 
When overlaying multiple 2D NMR spectra, one needs to supply a vector of colors for each spectrum contour,
as a list with length equal to the number of spectra to be plotted.
This is a convenience function which takes a vector of colors and copies it into a list, ready for
use with plotSpectra2D
.
LofC(cols, nspec = 1L, ncon = 1L, mode = 1L)
cols 
Character. A vector of color designations. 
nspec 
Integer. The number of spectra to be plotted. 
ncon 
Integer. The number of contour levels. 
mode 
Integer. How to replicate the colors:

A list of length nspec
, the number of spectra to be plotted; each entry is a vector of colors.
