assertive (version 0.3-0)

assert_all_are_email_addresses: Does the character vector contain email addresses?

Description

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

Usage

assert_all_are_email_addresses(x, method = c("simple", "rfc5322"),
  na_ignore = FALSE)

assert_any_are_email_addresses(x, method = c("simple", "rfc5322"),
  na_ignore = FALSE)

is_email_address(x, method = c("simple", "rfc5322"),
  .xname = get_name_in_parent(x))

Arguments

x

Input to check.

method

Name of method to check for validity. See notes below.

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.

.xname

Not intended to be called directly.

Value

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

  punct    = "a!$&@b.com",
  missing  = NA
)
is_email_address(addresses)
is_email_address(addresses, method = "rfc5322")
