Seeing as there is no source code, I'm taking a stab in the dark, but
the below gives me a pie chart:
to <- as.POSIXlt('23:59:59', format='%H:%M:%S', origin=Sys.Date())
from <- as.POSIXlt('00:00:00', format='%H:%M:%S', origin=Sys.Date())
range <- seq(from, to, by = .5)
dallas <- data.frame(offense_hour = range, stuff = rnorm(c(1:length(range))))
p <- ggplot(dallas, aes(x = offense_hour) + geom_bar() + coord_polar)
