问题描述

一个朋友通过使用R 对NYtimes进行网络爬虫.我真的很想尝试.但是，第一步是从源代码安装一个名为RJSONIO的软件包.

A friend sent me along this great tutorial on webscraping NYtimes with R. I would really love to try it. However, the first step is to installed a package called RJSONIO from source.

我非常了解R，但是我不知道如何从源代码安装软件包.

推荐答案

如果您在本地拥有文件，则使用install.packages()并设置repos=NULL:

If you have the file locally, then use install.packages() and set the repos=NULL:

install.packages(path_to_file, repos = NULL, type="source")

path_to_file代表完整路径和文件名:

Where path_to_file would represent the full path and file name:

• 在Windows上，它看起来像这样:"C:\\RJSONIO_0.2-3.tar.gz".
• 在UNIX上，它看起来像这样:"/home/blah/RJSONIO_0.2-3.tar.gz".

• On Windows it will look something like this: "C:\\RJSONIO_0.2-3.tar.gz".
• On UNIX it will look like this: "/home/blah/RJSONIO_0.2-3.tar.gz".
