问题描述
我正在开发一个项目，需要运行一些R代码才能进行一些数据分析。该项目主要使用JavaScript，我需要一种从JS运行R代码的方法。我的研究还没有找到任何好办法。有没有办法这样做？
I am working on a project which requires some R code to be run for some data analysis. The project is primarily in JavaScript, and I need a way to run R code from JS. My research has not found any good way to do it yet. Is there any way to do so?
另外，我没有R的经验（另一个人正在提供R代码）。
Also, I have next to no experience with R (another person is supplying the R code).
推荐答案
如果您可以在服务器上运行R代码，那么您应该看一下。它提供了一个REST API和相应的JavaScript库，用于将R代码发送到服务器并获取结果。特别是，它处理了将R作为服务器运行时可能出现的安全问题（R代码可以运行任意shell命令等）。您可以使用公共演示实例进行尝试，并且提供了一个简单的教程。
If you're ok with having the R code run on a server, then you should take a look at OpenCPU. It provides a REST API and corresponding JavaScript library for sending R code to the server and getting the results back. In particular, it takes care of the security problems that can arise from running R as a server (R code can run arbitrary shell commands, among other things). There are public demo instances that you can use to try it out, and this page provides a simple tutorial.
