Defines a tuning grid from a set of parameters.

Usage

ParameterGrid(...)

ParameterGrid(object, size = 3, random = FALSE, ...)

Arguments

...	named param objects as defined in the dials package.
size	single integer or vector of integers whose positions or names match the given parameters and which specify the number of values used to construct the grid.
