I have the following data in which I'm trying to summarize in a stacked bar plot showing the percentages as a label in the bar. The data is as follows:> head(data)MASTERPAK2LT MASTERPAK4LT MASTERPAK7LT MASTERPAK10LT MASTERPAK22LT 1 X X X X X 2 C C C X X 3 C C C X X 4 U U X X X 5 <NA> U X X X 6 <NA> <NA> X <NA> <NA> It is then transformed using dplyer:> d2 <- data %>%gather(Model,Status) %>% group_by(Model,Status) %>% summarise(count=n()) %>% mutate(perc=count/sum(count)) giving> head (d2)Source: local data frame [6 x 4] Groups: Model [2] Model Status count perc <chr> <chr> <int> <dbl> 1 MASTERPAK10LT C 8 0.21052632 2 MASTERPAK10LT X 29 0.76315789 3 MASTERPAK10LT <NA> 1 0.02631579 4 MASTERPAK22LT C 6 0.15789474 5 MASTERPAK22LT U 1 0.02631579 6 MASTERPAK22LT X 30 0.78947368 I then try to plot this using ggplot using plt <- ggplot(d2,aes(x=Model,y= perc,fill=Status)) + geom_bar(stat="identity") + labs(y="Percent Complete") + stat_bin(geom = "text", aes(label=paste(round(perc*100),"%")), vjust=5) + scale_y_continuous(labels = percent) but I get the error: Error: stat_bin() must not be used with a y aesthetic. When I leave out the stat_bin, I get the correct bar chart, but without the labels. Can someone please help me understand what is causing the error above? Thank you kindly, Shawn Way, PE
I've never seen ? stat_bin used like that. What exactly is it supposed to
do. It looks like you are trying to label the %ages in each piece of the bar.

The data is as follows:

It is then transformed using dplyer:

? ? group_by(Model,Status) %>%
? ? summarise(count=n()) %>%
? ? mutate(perc=count/sum(count))
giving > head (d2)

6 MASTERPAK22LT? ? ? X? ? 30 0.78947368
I then try to plot this using ggplot using
plt <- ggplot(d2,aes(x=Model,y= perc,fill=Status)) +
? ? geom_bar(stat="identity") +
? ? labs(y="Percent Complete") +
? ? stat_bin(geom = "text",
? ? ? ? ? ? aes(label=paste(round(perc*100),"%")),
? ? ? ? ? ? vjust=5) +
? ? scale_y_continuous(labels = percent)
but I get the error:
Error: stat_bin() must not be used with a y aesthetic.
When I leave out the stat_bin, I get the correct bar chart, but without the
labels.? Can someone please help me understand what is causing the error above?
Thank you kindly,
