`stripqq()` is deprecated and is no longer exported. It draws strip
charts and normal quantile-quantile plots of `x` for each level of the
grouping variable `g`.
Arguments
- formula
A symbolic specification of the form x ~ g can be
given, indicating the observations in the vector x are grouped
according to the levels of the factor g. NAs are allowed in
the data.
- ...
Optional arguments that are passed to the stripchart function.
Note
This is a legacy teaching helper retained for compatibility with
older course material. New teaching material should prefer current
diagnostic plotting workflows.
