ggplot2无法识别闪亮的反应数据

Question

大家好！

我在这里努力获取我按“fc”函数分组的数据，并且它应该在这个新的数据集'reac'中，我希望它在用户输入变量时更新他/她想在闪亮的UI中使用（输入$ x，输入$ y，输入$ color）。然后我想在ggplot中使用这个新的rem数据集，但是'aes_string（）不起作用，编译器不能将数据类型识别为数据帧而且我得到一个“无法将NULL转换为quosure “错误和”未知输入：tbl_df“错误。

抱歉英语不好，这不是我的箴言！ ：（

提前致谢！

当我加载.Rdata并使用 Alejandro 建议的更改运行代码时，我的图表发生了变化。

加载了除sidrar和rsconnect之外的库，并运行代码：

library(shiny)
library(plotly)
library(dplyr)
library(ggplot2)
