R Studio F2 不再启动`View()` [英] R Studio F2 wont initiate `View()` anymore

问题描述

当我在键盘上按下 F2 时，它会以 Excel 类型的方式打开一个数据框.但有时它会打开这个(见下图).出了什么问题?

When I hit F2 on my keyboard it'll open up a data frame in an Excel type fashion. But sometimes it opens this (see image below) instead. What went wrong?

推荐答案

根据键盘快捷键 document，F2是显示光标处函数的源代码.如果突出显示(或将光标置于)数据帧变量上并按 F2，数据查看器将打开，您将看到 View(df) 命令在控制台中运行.同样，如果您突出显示或定位在函数名称上，您将看到该函数的源代码.

As per the keyboard shortcut document, F2 is to show the source code for function at cursor. If you highlight (or position the cursor on) a dataframe variable and press F2, the data viewer will open and you will see that the View(df) command ran in the console. Similarly, if you highlight or position on a function name, you will see the source code of that function.
