functions for extracting the core data contained in a colorSpec object.
# S3 method for colorSpec
coredata( x, forcemat=FALSE )# S3 method for colorSpec
as.matrix( x, ... )
If x has organization equal to 'vector' then it returns x,
unless forcemat is TRUE when it returns x as a matrix with 1 column.
If x has any other organization then it returns a matrix
with spectra in the columns.
All of the colorSpec attributes are stripped except the column names,
and the row names are set to as.character(wavelength(x)).
a wrapper for coredata with forcemat=TRUE
a colorSpec object
if x has only 1 spectrum, return a matrix with 1 column instead of a vector
