@rmpruzek writes that in classic `granova`, the function `granova.1w()` can print trimmed means for each group:

> A large thin green cross is used, printed at the end so it tends not to be overprinted.
> Easily seen if you run granova.1w and set tr=T. b

Here's what such a graphic (with trimmed means) looks like under classic `granova`:

```r
library(ggplot2)
library(granova)
with(mpg, granova.1w(hwy, group = manufacturer, tr = TRUE))
```
