Checks length is a particular value or range using
length(x) >= length && length(x) <= upper
chk_length(x, length = 1L, upper = length, x_name = NULL)vld_length(x, length = 1L, upper = length)
vld_length(x, length = 1L, upper = length)
The chk_ function throws an informative error if the test fails or returns the original object if successful so it can used in pipes.
