Check Vector
Checks if is a vector using
(is.atomic(x) && !is.matrix(x) && !is.array(x)) || is.list(x)
chk_vector(x, x_name = NULL) vld_vector(x)
x |
The object to check. |
x_name |
A string of the name of object x or NULL. |
is.vector(x) is not reliable because it returns TRUE only
if the object is a vector with no attributes apart from names.
The chk_ function throws an informative error if the test fails.
The vld_ function returns a flag indicating whether the test was met.
