gen_logical(n, ...)

gen_name(n)

Arguments

n: The size of the vector to generate
min: The minimum range for the vector
max: The maximum range for the vector
values: The explicit values to use.
...: Additional arguments passed to internal generation functions
f: The random function to use.
prob: a vector of probability weights for obtaining the elements of the vector being sampled.
levels: The explicit levels to use, if NULL random levels are generated using gen_name().
ordered: Should the factors be ordered factors?
num_levels: The number of factor levels to generate
fractional: Whether to generate times with fractional seconds
tz: The timezone to use for dates
