Question

Error: stat_count() must not be used with a y aesthetic.

The above error pops up while drawing bar graph. I used mpg dataset to draw bar chart of displ vs cyl.

Answer 1

Hi Rayan,

This error comes due to the mapping of elements in aes() while plotting barplot.

geom_bar by default takes a count of values as y in a bar plot. So use stat="identity" within barplot() to avoid the default and use fields as used in mapping function.

ggplot(data,aes(field1,field2)) +geom_plot(stat="identity")
