Return the data with the hard clustering assigments.

Extract the clustering assignments, and return the data. Assignments can be computed subsetting the mutations that have posterior values (reponsibilities) below a certain cutoff (default 0 - all assigments); non-assigned mutations have NA as cluster label.

Clusters(x, cutoff_assignment = 0)

Arguments

x	A MOBSTER fit.
cutoff_assignment	Cutoff to compute hard clustering assignments.

Value

The data stored in x$data with a column label reporting the assigned cluster, or NA if the maximum cluster probability is below the threshold value cutoff_assignment.

Examples
