messagef {pkgmaker}

General Log Formating

Description

Generate a formatted diagnostic message. This function is a shortcut for message(sprintf(...)).

Usage

messagef(fmt, ..., domain = NULL, appendLF = TRUE)

wnote(..., immediate. = TRUE)

Arguments

fmt

a character vector of format strings, each of up to 8192 bytes.

...

values to be passed into fmt. Only logical, integer, real and character vectors are supported, but some coercion will be done: see the ‘Details’ section. Up to 100.

domain

see gettext. If NA, messages will not be translated, see also the note in stop.

appendLF

logical: should messages given as a character string have a newline appended?

immediate.

logical, indicating if the call should be output immediately, even if getOption("warn") <= 0.

Value

Returns nothing. Used for their side effects of printing messages/warnings.

Functions

• wnote(): throws a simple note as an immediate warning. It is a shorcut for warning(..., immediate. = TRUE, call. = FALSE).
