ggplot_bar_stacked_dodged() creates a bar plot with both stacked (different categories atop each other) and dodged (different categories along the x-axis) positioning. Useful for showing more dimensions.

1	ggplot_bar_stacked_dodged(data, mapping)

`data`	a data frame
`mapping`	`aes()` mapping with aesthetics `x`, `y`, `fill` and `dodge`.

The fill dimension will be stacked and the dodge dimension spread along the x-axis. Use further ggplot2 functions like scales, themes and facets as usual. Automatically splits positive and negative values for plotting above and below zero bars.
