Thierry,
Thank you for such a quick response.
I changed the code, but I seem to get the same response. Ugh. Maybe I am
missing a step. Thank you again for any feedback.
Me_df<-data.frame(Data = c(1:15), Person = "Me")
You_df<-data.frame(Data = c(10:20), Person = "You")
Them_df<-data.frame(Data = c(15:25), Person = "Them")
Group_df_tmp<-rbind(Me_df,You_df)
Group_df<-rbind(Group_df_tmp,Them_df)
Group_df$Person <- factor(Group_df$Person, levels = c("Them", "You", "Me"))
counts <- ddply(Group_df, .(cut(Data, breaks=fullseq(range(Data), 5)), Person),
nrow)
names(counts) <- c("Bin", "Person", "Frequency")
qplot(Person, Frequency, data = counts, fill = Person, geom="bar",
stat="identity", width = 0.9, xlab="Person") + facet_grid(. ~ Bin)

Dear Jason,
Convert Person to a factor with the levels in the order that you want.
Group_df$Person <- factor(Group_df$Person, levels = c("Them",
"You", "Me"))
HTH,
Thierry

To call in the statistician after the experiment is done may be no more than
asking him to perform a post-mortem examination: he may be able to say what the
experiment died of.

Onderwerp: [R] A way to "lock down" the order of bars for ggplot
"dodged"histogram
It appears that ggplot reorder the data for a
"dodged" histogram based on whether or not a specific variable has a
value in the first bin.
I would like to be able to absolutely force the order of the variables in the
bin. For example, say I have three variables Me, You, and Them.
Me_df<-data.frame(Data = c(1:15), Person = "Me")
You_df<-data.frame(Data = c(10:20), Person = "You")
Them_df<-data.frame(Data = c(15:25), Person = "Them")
Group_df_tmp<-rbind(Me_df,You_df)
Group_df<-rbind(Group_df_tmp,Them_df)
counts <- ddply(Group_df, .(cut(Data, breaks=fullseq(range(Data), 5)),
Person), nrow)
names(counts) <- c("Bin", "Person",
"Frequency")
qplot(Person, Frequency, data = counts, fill = Person, geom="bar",
stat="identity", width = 0.9, xlab="Person") +
facet_grid(. ~ Bin)
However, I absolutely must have the bar order be Them, You, Me. Is there
a to fix the order of the bars so that they are always in the Them, You, Me
order?
Thank you again for any feedback you can provide.
