chk_vector | R Documentation |
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 or
returns the original object if successful so it can used in pipes.
The vld_
function returns a flag indicating whether the test was met.
