\title{
 Map matrix of probabilities to class assignments.
}
\description{
Traverse the rows of a matrix of probabilities of size n x k, where the n rows are samples, and the k columns are the probability of assignment of the sample to each of k classes. The most probable class assignment is selected for each row and a vector of classes is returned.
}
\usage{
map(z, ...)
