assert_all_are_numeric_strings {assertive.strings} | R Documentation |
Check to see if a character vector contains numeric/logical strings.

x |
A character vector. |
na_ignore |
A logical value. If |
severity |
How severe should the consequences of the assertion be?
Either |
.xname |
Not intended to be used directly. |
is_numeric_string
returns a logical vector that is TRUE
when the string contains numbers. The corresponding assert_*
functions return nothing but throw an error on failure.
