【问题描述】：
我正在尝试在 Ubuntu 14.04 上安装 R 3.0.2 devtools 包，如下所示：
install.packages("devtools")
我得到以下结果：
Installing package into ‘/home/jim/R/x86_64-pc-linux-gnu-library/3.0’
(as ‘lib’ is unspecified)
--- Please select a CRAN mirror for use in this session ---

似乎存在对名为 xml2 的包的依赖项。有谁知道我在哪里可以找到这个包以及如何安装它。
我已经安装了以下：
sudo apt-get install libxml2-dev
sudo apt-get install libcurl4-openssl-dev
sudo apt-get install libcurl4-gnutls-dev
sudo apt-get install curl
【问题讨论】：
-
从this Ubuntu repo on every CRAN mirror安装R 3.2.0；一切都会到位。
-
sudo apt-get update ... 然后 sudo apt-get install r-base ... 将安装以下新软件包：r-base 0 升级，1 新安装，0 删除和 3 没有升级。需要获取 0 B/9,568 B 的档案。此操作后，将使用 73.7 kB 的额外磁盘空间。选择以前未选择的包 r-base。 （正在读取数据库...当前安装的 201581 个文件和目录。） 准备解压 .../r-base_3.0.2-1ubuntu1_all.deb ... 解压 r-base (3.0.2-1ubuntu1) ... 设置 r -base (3.0.2-1ubuntu1) ... jim@Ubuntu14:~$ 3.0.2 仍在安装中
