assert_all_are_ip_addresses

From assertive.data v0.0-3 by Richard Cotton

Does the character vector contain IP addresses?

Checks that the input contains IP addresses. (It does not check that the address exists, merely that the string is in a suitable format.)

Usage

assert_all_are_ip_addresses(x, na_ignore = FALSE,
  severity = getOption("assertive.severity", "stop"))
assert_any_are_ip_addresses(x, na_ignore = FALSE,
  severity = getOption("assertive.severity", "stop"))
is_ip_address(x)

Arguments

x: Input to check.
na_ignore: A logical value. If FALSE, NA values cause an error; otherwise they do not. Like na.rm in many stats package functions, except that the position of the failing values does not change.
severity: How severe should the consequences of the assertion be? Either "stop", "warning", "message", or "none".

Value

A logical vector that is TRUE when the input contains valid IP addresses.

Note

Valid IP addresses are considered to be four integers in the range 0 to 255, separated by dots, or the string "localhost".

Examples

# NOT RUN {
x <- c(
  localhost     = "localhost", 
  valid_address = "255.0.255.0", 
  out_of_range  = "1.2.3.256",
  five_blocks   = "1.2.3.4.5",
  non_numeric   = "1.2.3.Z",
  missing_block = "1.2.3.NA",
  missing       = NA
)
is_ip_address(x)
assert_any_are_ip_addresses(x)
#These examples should fail.
assertive.base::dont_stop(assert_all_are_ip_addresses(x))
# }
