📜 "Implementing the R Pipe operator in vscode and Emacs"

September 18, 2018

In Rstudio, Ctrl - Shift - M inserts the %>% pipe command. Here I’ve just listed how to get similar functionality across a range of editors. The following scripts show how to implement the R pipe in Emacs and the Vscode.

R Pipe in Visual Studio Code

    {
        "key": "ctrl-shift-m",
        "command": "editor.action.insertSnippet",
        "args": {
            "snippet": "%>%"
        },
        "when": "editorLangId == 'r'"
}
