ggplot带R的分组条形图

我在创建分组的barplot时遇到困难.这是我第一次使用R中的散点图以外的其他任何东西.有团队，并且他们放弃了要靠位置的位置(代码下方).C，D和W.在r-graph-gallery中查找以下代码.

I am having difficulties creating a grouped barplot. This is my first time using anything other than the scatter plot in R. There is the Team, and the points they give up to the position(Below the Code). C, D, and W. Going off the r-graph-gallery for the code below.

library(ggplot2)
positions=rep(c("C","W","D"))

ggplot(data=stats, aes(fill=positions, y=0,200,x=PtsAgRdTm))+
  geom_bar(position = "dodge", stat = "indentity")

下面是 df 作为 stats 的数据，而不是转换为 data 的数据.

Below is the df as stats than converted to data.
