Check Whole Number
Checks if non-missing integer scalar or double equivalent using
vld_number(x) && (is.integer(x) || vld_true(all.equal(x, trunc(x))))
Pass: 1, 2L, 1e10, -Inf
Fail: "a", 1:3, NA_integer_, log(10)
chk_whole_number(x, x_name = NULL) vld_whole_number(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.
The vld_ function returns a flag indicating whether the test was met.
