The install.packages method
install.packages 方法
You need to install the ubuntu package libxml2-devSo in a shell prompt type:
你需要安装 ubuntu 包libxml2-dev所以在 shell 提示下输入：
sudo apt-get update
sudo apt-get install libxml2-dev
You will need special sudopowers for this.
sudo为此，您将需要特殊的权力。

As Richie and Dirk mentioned, you can also use:
正如 Richie 和 Dirk 提到的，您还可以使用：
sudo apt-get install r-cran-xml
If you go down this path, I would recommend that you check out the R ubuntu sourcespage which will ensure you have a current version of R and the associated R packages. This could be important if you are using the LTS version of ubuntu.
如果您沿着这条路走下去，我建议您查看R ubuntu 源页面，这将确保您拥有当前版本的 R 和相关的 R 包。如果您使用的是 ubuntu 的 LTS 版本，这可能很重要。

The answer by Colin is correct in a narrow sense, but at the same time wrong as you can just say
科林的答案狭义上是正确的，但同时你也可以说是错误的
sudo apt-get install r-cran-xml
as XML is one of the CRAN packages available in Ubuntu. Do apt-cache search r-cran-*do see the others.
因为 XML 是 Ubuntu 中可用的 CRAN 包之一。这样做apt-cache search r-cran-*确实看到了别人。
