Examples

if (FALSE) {
library(assertthat)
assert_that(is_bounded(10))
# TRUE

assert_that(is_bounded(10:30))
# TRUE

assert_that(is_bounded(Inf))
# Error: Inf is not bounded by (-Inf,Inf)

assert_that(is_bounded(10, lower_bound = 20))
# Error: 10 is not bounded by (20,Inf)

assert_that(is_bounded(
  10,
  lower_bound = 20,
  lower_closed = TRUE,
  upper_bound = 30,
  upper_closed = FALSE
))
# Error: 10 is not bounded by [20,30)
