R中的文件浏览器 [英] File browser in R

问题描述

我需要为从未使用过R的人编写一个小的R脚本，然后再导入文件并对其执行某些操作.我想尽可能地减少用户输入，并且由于分配文件路径基本上是我想知道的所有用户输入，因此是否有可能获得一个弹出屏幕(基本上是您通常的打开文件"屏幕)，允许某人选择一个文件(将名称导入为R或其他形式的字符串)?

I need to write a small R script for people who never used R before that imports a file and does some things with it. I would like to minimize user input as much as possible, and since assigning the file-path is basically all the user input required I was wondering, is it possible to get a popup screen (basically your usual "open file" screen) allowing someone to select a file (import the name as string in R or something)?

推荐答案

file.choose函数执行此操作，例如:

The file.choose function performs this, eg:

fname <- file.choose()

source(file.choose())

您可能还希望查看choose.files(用于多个文件)和choose.dir(仅用于选择目录路径).

You may also want to look at choose.files (for multiple files) and choose.dir (for just selecting a directory path).
