Broke ggplot...

It appears I broke ggplot in my script, but that maybe it is because the caffeine has worn off or maybe it is late in the day. I thought I was beginning to understand ggplot, but I have encountered a silly little issue. For some reason the following does not produce a histogram with fill due to the Person's characteristics: (Note that VADeaths_flat_df$Data works fine...) VADeaths_df<-data.frame(VADeaths)

You can do this a bit more easily with:
VADeaths_flat_df <- melt(VADeaths)
names(VADeaths_flat_df) <- c("Age", "Person", "Data")
bin_size<-15.0 ggplot(VADeaths_flat_df, aes(x = factor(Data), fill = factor(Person))) + geom_bar(position=position_dodge(width =(20)), binwidth=20) # or ggplot(VADeaths_flat_df, aes(x=factor(Data))) + geom_histogram(binwidth=20)
Those plots look fine to me (well they're what I'd expect from the definition), but I'd think you'd want ggplot(VADeaths_flat_df, aes(Data, fill = Person)) + geom_histogram(binwidth=20) or maybe ggplot(VADeaths_flat_df, aes(Person, weight = Data)) + geom_bar() ggplot(VADeaths_flat_df, aes(Person, weight = Data, fill = Age)) + geom_bar() Hadley
