ggplot报错 stat_count() can only have an x or y aesthetic

在使用ggplot画柱状图的时候,发生了报错:tat_count() can only have an x or y aesthetic.

#画图用的矩阵
> b3name      mean     lcl95   ucl95    p_valueCT 0.8882961 0.2329421 1.54365 0.02816491
ref  gap         1         1       1          0
#代码如下
> p <- ggplot(b3, aes(x=name,y=mean))
> p+geom_bar()
Error in `f()`:
! stat_count() can only have an x or y aesthetic.
Run `rlang::last_error()` to see where the error occurred.

To deal with Error: stat_count() can only have an x or y aesthetic, we need to pass the stat=“identity” argument inside geom_bar function. Since we do not pass the count for bars and a bar graph can only contain only count variable, hence stat=“identity” is needed so that geom_bar considers only one variable in aes for counting. Check out the below example to understand the difference.
要传递 **stat=“identity”**这个参数

> p <- ggplot(b3, aes(x=name,y=mean))
> p+geom_bar(stat = "identity")
> #成功!
