ParameterGrid(..., size = 3, random = FALSE, length = NULL)
# S3 method for list
ParameterGrid(x, size = 3, random = FALSE, length = NULL, ...)
# S3 method for parameters
ParameterGrid(x, size = 3, random = FALSE, length = NULL, ...)

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 to use in constructing a regular grid if random = FALSE; ignored otherwise.
