An object of this class is returned by a call to smooth_sam. It holds a smoother version of a SAM object, keeping only the clusters slot and slicing it to a user-given number of slices. This class have methods to plot, summarize, and extract the readings of pixel matching a given SpectralReference substance. You can use the generics plot, summary, and get_profile but beware, you might have to provide extra arguments! (so, please don't see only the generic but the method for this class, see the section see also).
