chk_lgl | R Documentation |
Checks if logical scalar using
is.logical(x) && length(x) == 1L
If you only want to check the data type (not whether length(x) == 1
),
you should use the chk_logical()
function.
chk_lgl(x, x_name = NULL)
vld_lgl(x)
x |
The object to check. |
x_name |
A string of the name of object x or NULL. |
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.
