get_batch_sizes(object, x, frac = c(1/10, 1/3), ...)A param object or a list of param objects.
The predictor data. In some cases (see below) this should only include numeric data.
A double for the fraction of the data to be used for the upper
bound. For get_n_frac_range() and get_batch_sizes(), a vector of two
fractional values are required.
Other arguments to pass to the underlying parameter
finalizer functions. For example, for get_rbf_range(), the dots are passed
along to kernlab::sigest().
