This is a wrapper around fastICA
from the package fastICA to be used with objects of class hyperSpec.
ica(x, ncomp, prefix = "basis", ...)
| x | a hyperSpec object. |
|---|---|
| ncomp | integer; number of pure components. |
| prefix | character; a prefix to name the pure spectra. |
| ... | further arguments to be passed down to |
a list with the following components:
coefficient matrix
a hyperSpec object containing the basis (component) spectra
the ica fit as returned by fastICA
