The type of signal depends on the class of the condition:

• A message is signalled if the condition inherits from "message". This is equivalent to signalling with inform() or base::message().

• A warning is signalled if the condition inherits from "warning". This is equivalent to signalling with warn() or base::warning().

• An error is signalled if the condition inherits from "error". This is equivalent to signalling with abort() or base::stop().

• An interrupt is signalled if the condition inherits from "interrupt". This is equivalent to signalling with interrupt().

Use cnd_type() to determine the type of a condition.

cnd_signal(cnd, .cnd, .mufflable)

## Arguments

cnd A condition object (see cnd()). These arguments are deprecated.

## Lifecycle

• .cnd has been renamed to cnd and is deprecated as of rlang 0.3.0.

• The .mufflable argument is deprecated as of rlang 0.3.0 and no longer has any effect. Non-critical conditions are always signalled with a muffle restart.

• Creating a condition object with cnd_signal() is deprecated as of rlang 0.3.0. Please use signal() instead.

## See also

abort(), warn() and inform() for creating and signalling structured R conditions. See with_handlers() for establishing condition handlers.

## Examples

# The type of signal depends on the class. If the condition
# inherits from "warning", a warning is issued:
cnd <- warning_cnd("my_warning_class", message = "This is a warning")
cnd_signal(cnd)#> Warning: This is a warning
# If it inherits from "error", an error is raised:
cnd <- error_cnd("my_error_class", message = "This is an error")
try(cnd_signal(cnd))#> Error : This is an error
