suppress_specific_warnings() will suppress warnings that match regular
expression patterns that are either coded into the function or supplied via
the patterns argument, without suppressing warnings that don't match the
patterns.
Usage
suppress_specific_warnings(x, patterns = NULL)
Arguments
- x
An expression.
- patterns
One or patterns to check warning messages against.
Value
Possibly output from x
Details
It's initial (possibly only) use is to catch a warning thrown by ggplot due
to NA value created by using lead() when plotting time of day.
suppress_specific_warnings() is used in the rmarkdown report so needs
to be a public function but it is not intended for external use.
Examples
suppress_specific_warnings(warning("this is a warning"), "this is")
suppress_specific_warnings(warning("this is a warning"))
#> Warning: this is a warning
