如何在不打开 PC 的情况下安排 R 代码运行?[虚拟主机] [英] How can i schedule an R code to run without having my PC on? [web-hosting]

问题描述

我想知道是否有可能将相对简单的 R 代码拉取并将数据输入到说......附加到电子邮件的文本文件，而不必让我的电脑保持开机状态.

I am wondering if it's possible to have relatively simple R code pull and feed data into say... a text file attached to an email without having to keep my PC on.

我这里有一个网页抓取代码，它使用:

I have a web-scraping code here that use:

library(XML)
library(stringr)

抓取一些我想每天保存的网络数据..

to scrape some web data which i would like to save daily..

将其置于每 24 小时运行一次的循环中相对容易，但我不想在运行时保持我的 PC 开启或无法使用 R 环境.

Putting that on a loop that runs every 24 hours would be relatively easy, but i don't want to keep my PC on or not able to use the R environment while this is running.

我有哪些选择?

推荐答案

建议您启动 AWS EC2 实例并将脚本设置为每天作为 cron 作业运行.

Suggest you spin up an AWS EC2 instance and set the script to run as a cron job on a daily basis.
