How do I extract the mean values (displayed in points) from the boxplot to a new dataframe?

Using code:

```
ggplot (df, aes(x = Place, y= C2.dn, fill = Consonant)) + 
geom_boxplot() + stat_summary(fun= "mean", position = position_dodge(width = 0.75))

```

I wish to extract the mean values (which is duration in milliseconds) for 'Consonant' (Singleton/Geminate) spoken at different 'Place'.

Data:
