Usage

Value

TRUE if x passes the check, else FALSE.

Arguments

Details

Checks whether the provided object can be handled by order. A couple of basic types are whitelisted. However, custom types can be defined when they provide a dedicated generic to xtfrm. Note that a list can only be sorted with atomic values. See the examples below for a template.

Examples

x <- Sys.time() + 5:1 * 3600 * 24
sort(x)
is_sortable(x)
