我正在使用ggplot2来制作直方图:
geom_histogram(aes(x=...), y="..ncount../sum(..ncount..)")
我收到错误:
Mapping a variable to y and also using stat="bin".
With stat="bin", it will attempt to set the y value to the count of cases in each group.
This can result in unexpected behavior and will not be allowed in a future version of ggplot2.
If you want y to represent counts of cases, use stat="bin" and don't map a variable to y.
If you want y to represent values in the data, use stat="identity".
See ?geom_bar …
