Random and regular grids can be created for any number of parameter objects.
Usage
grid_regular(..., levels = 3, original = TRUE)
grid_random(..., size = 5, original = TRUE)
Arguments
...
One or more param objects (such as mtry() or
penalty()). None of the objects can have unknown() values in
the parameter ranges or values.
levels
An integer for how many value of each parameter will be used
to make the regular grid? levels can be a single integer or a vector of
integers that is the same length as the number of parameters in ....
original
A logical: should the parameters be in the original units or
in the transformed space (if any)?
size
A single integer for the total number of parameter values
returned for the random grid.
Value
A tibble with an additional class for the type of type of grid
("grid_regular" or "grid_random"). There are columns for each parameter and
a row for every parameter or parameter combination.
