Assert input is greater than or equal to a specified minimum value

Assert all elements in a numeric vector/matrix are above some minimum value.

Usage

assert_all_greater_than_or_equal_to(
  x,
  minimum,
  msg = NULL,
  call = rlang::caller_env(),
  arg_name = NULL
)

Arguments

x

An object to check

minimum

The minimum value to compare against

msg

A character string containing the error message to display if x is not greater than or equal to the specified minimum value (string)

call

Only relevant when pooling assertions into multi-assertion helper functions. See cli_abort for details.

arg_name

Advanced use only. Name of the argument passed (default: NULL, will automatically extract arg_name).

Value

invisible(TRUE) if x is greater than or equal to the specified minimum value, otherwise aborts with the error message specified by msg

Examples

try({
assert_greater_than_or_equal_to(3, 2) # Passes
assert_greater_than_or_equal_to(c(3, 4, 5), 2) # Passes
assert_greater_than_or_equal_to(2, 3) # Throws error
})
#> Error in eval(expr, envir) : 
#>   'c(3, 4, 5)' is not a number! (length is 3, not 1)
