Check Date Time

Checks if non-missing POSIXct scalar using

inherits(x, "POSIXct") && length(x) == 1L && !anyNA(x)

Usage

chk_date_time(x, x_name = NULL)

chk_datetime(x, x_name = NULL)

vld_date_time(x)

vld_datetime(x)

Arguments

x

The object to check.

x_name

A string of the name of object x or NULL.

Value
