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)
vld_vector(x)
The chk_ function throws an informative error if the test fails or returns the original object if successful so it can used in pipes.
chk_
The vld_ function returns a flag indicating whether the test was met.
vld_
The object to check.
A string of the name of object x or NULL.
vld_vector(): Validate Vector
vld_vector()
is.vector(x) is not reliable because it returns TRUE only if the object is a vector with no attributes apart from names.
is.vector(x)
Other chk_is: chk_array(), chk_atomic(), chk_data(), chk_function(), chk_is(), chk_matrix(), chk_numeric(), chk_s3_class(), chk_s4_class(), chk_whole_numeric()
