Converts a matrix of class assignments to a vector of labels.
1 | mixmodMap_M2V(M, n = nrow(M), K = ncol(M))
|
M |
matrix of class assignments. Rows correspond to observations and columns correspond to classes. Each row contains only zeros except for the column corresponding to the class to which the observation is assigned, which value is one. |
n |
number of observations. |
K |
number of classes. |
a vector of labels of length n.
