In almanac: Tools for Working with Recurrence Rules

`count` can only be set once

Code
  daily() %>% recur_for_count(2) %>% recur_for_count(2)
Condition
  Error in `recur_for_count()`:
  ! The "count" rule is already set and can't be set twice.

`count` must be castable to a scalar integer

Code
  (expect_error(daily() %>% recur_for_count("a")))
Output
  <error/rlang_error>
  Error in `recur_for_count()`:
  ! `n` must be a whole number, not the string "a".
Code
  (expect_error(daily() %>% recur_for_count(c(1, 2))))
Output
  <error/rlang_error>
  Error in `recur_for_count()`:
  ! `n` must be a whole number, not a double vector.
