Operates a continuum removal on a vector.
a numeric vector
the wavelengths of the spectra
if TRUE, removes the upper convex hull from the spectra, if FALSE, takes the lower convex hull
This operation is commonly done to normalize reflectance spectra and allow comparison of individual absorption features from a common baseline. The removal is based on the upper convex hull of the spectra.
This function is working on vectors. It may applied on matrix or data.frames
apply function, or on
Spectra* objects using the
A numeric vector with its continuum removed.
