R: Diagnostic Messages

message {base} | R Documentation

## 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"))
