When plotting a barchart with ggplot it drops the levels of the factor for
which no counts are available.
This shows my problem. Because no counts are available for factorlevel '4',
the label 4 dissapears from the plot. However, I would still like it to show
up, but without a bar (zero observations).
I would like to use this for the presentation of data with a Likert-like
Thanks in advance!
