Diagnostic Messages

Description:

     Generate a diagnostic message from its arguments.

Usage:

     message(..., domain = NULL)
     suppressMessages(expr)

Arguments:

     ...: character vectors (which are pasted together with no
          separator), a condition object, or 'NULL'.

  domain: see 'gettext'. If 'NA', messages will not be translated.

    expr: expression to evaluate.

Details:

     'message' is used for generating "simple" diagnostic messages
     which are neither warnings nor errors, but nevertheless
     represented as conditions.

     While the message is being processed, a 'muffleMessage' restart is
     available.

     'suppressMessages' evaluates its expression in a context that
     ignores all "simple" diagnostic messages.

See Also:

     'warning' and 'stop' for generating warnings and errors;
     'conditions' for condition handling and recovery.

     'gettext' for the mechanisms for the automated translation of
     text.

Examples:

     message("ABC", "DEF")
     suppressMessages(message("ABC"))
