object
check_dtt(x, values = NULL, nas = TRUE, length = NA, unique = FALSE, sorted = FALSE, floored = FALSE, complete = FALSE, tz = dtt_tz(x), units = dtt_units(x), named = NA, x_name = substitute(x), error = TRUE)
x | The object to check. |
---|---|
values | NULL or a vector specifying the values. |
nas | A flag indicating whether missing values are permitted. |

unique | A flag indicating whether the values must be unique. |
sorted | A flag indicating whether the vector must be sorted. |
floored | A flag indicating whether x should be floored. |
complete | A flag indicating whether x should be complete. |
tz | A string of the time zone. |
units | A string of the units. |
named | A flag indicating whether the vector must be named or unnamed or NA if it doesn't matter. |
x_name | A string of the name of the object. |
error | A flag indicating whether to throw an informative error or immediately generate an informative message if the check fails. |
