R 使用ggplot2时出错：can'；找不到'stat'调用'quot；“身份”；

我在我的网络电话中没有找到任何结果。如何修复导致此错误的原因

library(ggplot2)
ggplot(data = mtcars, aes(x=disp , y=wt)) +
geom_point(stat = "identity")

结果

错误：找不到名为“标识”的

stat

我的

sessionInfo（）

我无法重现此错误，即使我附加了光泽。我只能得出结论，有些事情你没有告诉我们。您是否尝试重新启动R？是的，我重新启动了R。您是否重新启动R，然后重新安装ggplot2？我两者都无法复制，但我仍在使用shiny 1.1.0，您是否可以尝试降级shiny？
