Question

我在互联网上寻找解决问题的2天没有成功。我在工作中下载了Rstudio，并尝试安装一些软件包。

当我举例说R：

> install.packages("readxl")

返回

我查看了互联网，问题似乎是与我公司代理的连接（每次连接到互联网时都要输入用户名和密码）

我尝试添加C：\ Users \您的用户名\ Documents中的.Renviron文件，并在Internet上找到以下代码：

options(internet.info = 0)   
http_proxy = https:// user_id:password@your_proxy:your_port    
http_proxy_user = user_id:password

我替换了user_id和密码
我找到了我的代理：start＆gt; run＆gt; cmd＆gt; ipconfig它的格式为xxxxx.xxx.ca（有些字母替换了＆＃39; x＆＃39;）
而对于我的端口我放了8080

我也尝试直接下载包的zip文件，但它既不起作用。

我迫切希望找到解决方案

您是否尝试将<?php $connect = mysqli_connect( "localhost", "user", "password", "db" ); $sql = "SELECT * FROM current_rates WHERE date = '2017-05-01'"; $result = mysqli_query( $connect, $sql ); $Json_array = array(); while ( $row = mysqli_fetch_assoc( $result ) ) { $Json_array[] = $row; } /* echo "<pre>"; print_r($Json_array); echo "<pre>"; */ $finalJson['lenders'] = $Json_array; echo json_encode( $finalJson ); ?>放入.Renviron？

使用代理连接的Rstudio问题下载包
