Hi
Can anyone please see why the error occurs?
ggplot(moviedata, aes(x= year, y=screens))+
stat_boxplot(geom= 'errorbar')+
geom_boxplot()+
theme_bw()+
labs(title = "movie Genre by the year")+
xlab("year")+
ylab("genre")+
ylim(5,25)
Error: Discrete value supplied to continuous scale
Hard to tell w/o knowing what your data looks like, but I suspect screens
is stored as a factor or character. What does str(moviedata)
tell you?

the field screens
is being stored as discrete values (Factors). You can't create a boxplot where the y data is discrete. If the data in screens
can be converted to a number, you should do so. But you should really look at the data to make sure that makes sense.
