random_test_numbers: create extreme random numbers

Description

create random Dates, POSIX dates, letters and numbers. The numbers explore limits of R precision and floating point and integer ranges. Zero, negatives, positives.

Usage

random_test_numbers(n = n_rnd, min = NULL, max = NULL, hole = NULL)
random_test_integers(n = n_rnd, min = -.Machine$integer.max,
  max = .Machine$integer.max, hole = NULL)
random_test_letters(n = n_rnd, max_str_len = 257)

Arguments

n

integer number of each group to generate

min

optional minimum number

max

optional maximum number

hole

is a closed range of numbers not to include, e.g. c(1,2) would discard 1, 1.1 pi/2 and 2

max_str_len

integer scalar, maximum length of possible strings created, as distinct from number of strings given by n

Value

vector length 5n+1 containing variety of difficult numbers for testing purposes
