 \description{
-\code{data.table} provides specific condition classes for common operations, making it easier to handle errors programmatically. This is particularly useful when writing robust code or packages that use \code{data.table}. Relying on the exact text of error messages is fragile (it is not uncommon to change the wording slightly, or for the user's session not to be in English); prefer using the signal class where possible.
