R/als.R
als.RdThis is a wrapper around a modified version of doALS from the package alsace to be used with objects of class hyperSpec.
als(x, ncomp = NULL, basis_init = NULL, prefix = "basis")
| x | a hyperSpec object. |
|---|---|
| ncomp | integer; number of pure components, does not need to be specified if basis_init is provided. |
| basis_init | a hyperSpec object; initial estimates of pure spectral components,
if basis_init is NULL, initial components are estimated
using |
| prefix | character; a prefix to name the pure spectra. |
a list with the following components:
coefficient matrix
a hyperSpec object containing the basis (component) spectra
a named vector containing lof, rms and r2
the als fit as returned by the custom wrapper around `ALS::als()`
