random_test_numbers: create extreme random numbers

In jwutil: Tools for Data Manipulation and Testing

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
