A set of unnamed generators. The generated tibbles will be built
with random combinations of these generators.
rows
Number of rows of the generated data frame.
If rows is a single number all data frames will have
this number of rows. If rows is a numeric vector of
length 2 it will produce data frames with rows between
a minimum and maximum, inclusive. For example
rows = c(1L, 10L) would produce data frames with rows
between 1 and 10. To produce empty tibbles set rows = 0L
or a range like rows = c(0L, 10L).
cols
Number of columns of the generated data frame.
If cols is a single number all data frames will have
this number of columns. If cols is a numeric vector
of length 2 it will produce data frames with columns
between a minimum and maximum, inclusive. For example
cols = c(1L, 10L) would produce data frames with
columns between 1 and 10. To produce empty tibbles
set cols = 0L or a range like cols = c(0L, 10L).
