Generic function to fit models - inherited from estimator
fit(x, model, y = NULL, ...)# S3 method for Matrix
fit(x, model, y = NULL, ...)
# S3 method for matrix
fit(x, model, y = NULL, ...)
a matrix like object, should inherit from Matrix or matrix
instance of class estimator which should implement method
with signature $fit(x, y, ...)
NULL by default. Optional response variable for supervised models.
Should inherit from vector Matrix or matrix. See documentation
for corresponding models.
