Checks to see if the input is complex.
1 2 3 4 5 6 7 | assert_is_a_complex(x, severity = getOption("assertive.severity", "stop"))
assert_is_complex(x, severity = getOption("assertive.severity", "stop"))
is_a_complex(x, .xname = get_name_in_parent(x))

|
x |
Input to check. |
severity |
How severe should the consequences of the assertion be?
Either |
.xname |
Not intended to be used directly. |
is_complex
wraps is.complex
, providing more
information on failure. is_a_complex
returns TRUE
if the
input is complex and scalar. The assert_*
functions return
nothing but throw an error if the corresponding is_*
function
returns FALSE
.
is.complex
and is_scalar
.

#These examples should fail.
