....你有一些问题正在运行ggplot2，我正在尝试通过一个基本的在线教程然后问题，试图在其中一个练习中运行qplot然后我得到错误上面列出的，我已经阅读了以前的帮助查找，经历了以下动议：

install.packages("proto")
install.packages('ggplot2', dep = TRUE)，
重新启动R - 仍然收到错误。还有其他“回答”吗？

Answer 1

安装ggplot2后我遇到了同样的错误。解决这个问题的两种方法：

1）你需要在调用qplot（）之前加载“library（ggplot2）”

library(ggplot2)
qplot(factor(CLASS), VOLUME, data = abalone, geom = "boxplot")

2）我随机发现在你的代码前添加“ggplot2 ::”也可以使它工作，而无需调用库。

ggplot2::qplot(factor(CLASS), VOLUME, data = abalone, geom = "boxplot")

R中出错 - [错误：找不到功能“qplot”]
