In kerasR: R Interface to the Keras Deep Learning Library

Converts a class vector (integers) to binary class matrix.

Description

This function takes a vector or 1 column matrix of class labels and converts it into a matrix with p columns, one for each category. This is the format most commonly used in the fitting and predicting of neural networks.

y	class vector to be converted into a matrix (integers from 0 to num_classes).
num_classes	total number of classes. Set to NULL to autodetect from the input.
