arg_match0_integer: Match an argument to a integer vector but skip NA

Description

This is equivalent to arg_match but an integer variable is needed and skip NA.

Usage

arg_match0_integer(
  arg,
  values,
  allow_na = TRUE,
  arg_nm = rlang::caller_arg(arg),
  error_call = rlang::caller_env()
)

Value

The integer supplied to arg.

Arguments

arg

A symbol referring to an argument accepting strings.

values

A character vector of possible values that arg can take.

allow_na

Input boolean to determine if NA or NaN is allowed. Default: TRUE

arg_nm

Same as error_arg.

error_call

The execution environment of a currently running function, e.g. caller_env(). The function will be mentioned in error messages as the source of the error. See the call argument of abort() for more information.

Examples

# No error
input = 5
arg_match0_integer(input, values = c(0:5))

# Allow NA
input = NA
arg_match0_integer(input, values = c(0:5))

# Error as 0 is not within 0 and 5
input = 6
try(arg_match0_integer(input, values = c(0:5)))

# Error as NULL is not within 0 and 5
input = NULL
try(arg_match0_integer(input, values = c(0:5)))

# Error as NA is not within 0 and 5 and allow_na is FALSE
input = NA
try(arg_match0_integer(input, values = c(0:5), allow_na = FALSE))
