I cannot figure out how to draw a certain plot: could someone help me out?
I have this data.frame from a survey
that looks like something like this:
col1 col2 col3 col4
1 5 5 4 5
2 3 5 3 1
3 2 3 4 5
4 3 1 1 2
5 5 5 4 5
6 4 2 5 5
Each row represents a single questionnaire with someone giving his
agreement/disagreement with a statement (each column is a statement) that is
coded from 1 to 5.
I need to draw a barplot giving a visual representation showing differences
between the five columns: Each bar should represent a single column, and
should be divided into 5 sections, the thickness of each depending on the
number of respondents who choose that particular answer.
How do I do that? All I have managed to do so far is to produce a barplot of a
single column, and that - only with bars side by side...
