在RStudio中执行几行的快捷方式 [英] Shortcut for executing several lines in RStudio

问题描述

我正在使用 RStudio ，通常使用 Crtl + Enter 逐行运行我的代码.通常，这可以正常工作，但可以正常运行 dplyr ，我想运行我使用管道运算符％>％，

I'm using RStudio and normally run my code line by line, using Crtl + Enter. In general this works fine but working dplyr I would like to run a whole code-section I wrote using the pipe-operator %>%,

例如我想立即执行以下代码段，最好独立于管道代码行中的当前光标位置:

For e.g. I'd like to execute the following code-section at once, at the best independently from the current cursor position within the piped codelines:

mtcars %>%
  filter(carb >= 2) %>%
  group_by(cyl) %>%
  summarise(mean.hp = mean(hp))

我可以逐行运行或标记所有行，然后按 Crtl + Enter ，但这两种方式都令人讨厌.搜索互联网和"工具/修改键盘快捷键"中可用的RStudio选项，我只发现了其他选项，例如运行整个部分，即

I could run this line by line or mark all lines and then press Crtl + Enter but both ways are some kind of annoying. Searching the internet and the RStudio-options available in "Tools/Modify Keyboard Shortcuts" I only found other options like running a whole section, that is starting at

# Example section--------------------

推荐答案

将光标置于代码块中的任意位置，并使用 Crtl + Shift + ↑(按住 Crtl 和 Shift ，然后按↑按钮).第一次将放置光标的单词加亮显示，然后在重复时将整个代码块加亮显示.如果您有一个嵌套循环或其他嵌套结构，则会突出显示整个最里面的循环，然后是第二个最里面的循环，等等.

Place cursor anywhere in the code chunk and use Crtl + Shift + ↑ (hold down Crtl and Shift, then push ↑ button). The first time the word in which the cursor is placed gets highlighted, then, when repeted, the whole chunk of code gets highlighted. If you have a nested loop or another nested structure this will highlight the whole innermost loop, then the second inner most loop etc.

突出显示代码后，可以按 Crtl + Enter 执行代码.

When you have the code highlighted you can press Crtl + Enter to execute the code.
