Werner,
Yes, it exists. See the likert function in the HH package.
Run the examples in the help file ?likert and the demo to see all the
capabilities of the
likert function, particularly multiple groupings within the sample
population.
Discussion and example of multiple groupings are included in the examples.
Links to our (with Naomi Robbins) publications showing the graphs are in
the help file.
Our 2012 JSM contributed paper will be out soon. All the graphs in that
paper can be
created using the command
demo("likert-paper")
The third item in Jose Iparraguirre's response uses our function.
http://stackoverflow.com/questions/12272704/visualization-of-likert-responses-using-net-stacked-bar-charts-how-to-compare-b
This response is incomplete, as the likert function does handle grouped
responses very
well. The first graph in demo("likert-paper") has that form.
Please feel free to write me should you need elaborations not illustrated
there.
