我遇到同样的问题
p <- ggplot(diamonds,aes(x=carat,y=price,colour=cut))
p <- p + layer(geom="point")
错误: Attempted to create layer with no stat.
请问您现在有没有解决这个问题呢？

ggplot(diamonds,aes(carat,price,colour=cut))+geom_point()，ggplot2出版这么多年了，应该是更新过

P<-p+geom_point()即可

也遇到了此问题

stat ="identity" 加这个就可以

position ="identity" ,stat ="identity"   这两个都加上就OK了

position =&quot;identity&quot; ,stat =&quot;identity&quot;   这两个都加上就OK了

你好，我按照您说的加上了，不报错了，但是不出图呀

我这边没问题。你再查一下别的原因吧。
