capture_condition.Rd
These functions allow you to capture the side-effects of a function call
including printed output, messages and warnings. We no longer recommend
that you use these functions, instead relying on the expect_message()
and friends to bubble up unmatched conditions. If you just want to silence
unimportant warnings, use suppressWarnings()
.
capture_condition(code, entrace = FALSE) capture_error(code, entrace = FALSE) capture_expectation(code, entrace = FALSE) capture_message(code, entrace = FALSE) capture_warning(code, entrace = FALSE) capture_messages(code) capture_warnings(code)
code | Code to evaluate |
---|---|
entrace | Whether to add a backtrace to the captured condition. |
Singular functions (capture_condition
, capture_expectation
etc)
return a condition object. capture_messages()
and capture_warnings
return a character vector of message text.
