I'm not sure I know yet what I'm looking for. :-) I have a list of all traffic tickets written in Dallas, TX over a few years. One of the first things I am doing is reviewing the data to make sure the quality is good; I'm trying to see whether it just looks right.
One measure is whether the volume of tickets written each hour of the day make sense. I've converted each ticket's time into a times class (from the chron package). The problem is that this is expressed as a decimal value between 0 and 1. For example, take 0.538194444444444. That is the underlying value behind a times object. 0.538194444444444 * 24 = 12.916666666666656. OK, so this is 12 noon and some minutes. 0.916666666666656 * 60 = 55. OK, it's 12:55 PM. Now if I put these times in a barplot, I'd like to group by each hour, which would be increments of 1/24 = 0.041667. And I'd like the labels on the X axis to be like 1 AM, 2 AM, 3 AM instead of 0.041667, 0.08333, and 0.125. I'm not clear how to do this with ggplot.
