shiny 学习lesson2 作业第二节课的学习时间比较长，所以作业也要好好的上交一下，本来想自己制作一个火山图制作的用户界面，可是在Windows的操作系统上，shiny不支持中文，使用默认编码方式，只要运行就会报错，使用utf-8的编码方式，不会报错，界面也显示中文，可是代码里的中文就会变成乱码，下次试试Linux系统，看看这种情况能不能解决。所以这次的作业就中规中矩的做了shiny学习上要求的网页，心有不甘，肯定会补上自己的中文页面！ library(shiny) ui <- fluidPage( titlePanel 阅读详情

1 安装软件包的三种方法

rpm工具

RPM包是预先在Linux机器上编译并打包的文件，安装非常快捷。但它也有一些缺点，比如安装环境必须与编译时的环境一致或者相当，包与包之间存在着相互依赖的情况，卸载包时需要先把依赖的包卸载。如果依赖的包是系统所必需的，就不能卸载这个包，否则系统会崩溃。

yum工具

yum工具最大的优势在于可以联网去下载所需要的RPM包，然后自动安装。如果要安装的RPM包有依赖关系，yum工具会帮我们依次安装所有相关的RPM包

源码包

安装源码包，需要我们把源代码编译成可执行的二进制文件。如果你能读懂这些源代码，就可以修改这些源代码的自定义功能，然后再按你的需求编译。使用源码包除了可以自定义修改源代码外，还可以定制相关的能，因为源码包在编译时可以附加额外的选项

2 rpm包介绍

[root@worker1 mnt]# mount /dev/cdrom /mnt/
mount: /dev/sr0 is write-protected, mounting read-only
[root@worker1 mnt]# cd /mnt/Packages/
[root@worker1 Packages]# ls | head
389-ds-base-1.3.4.0-19.el7.x86_64.rpm
389-ds-base-libs-1.3.4.0-19.el7.x86_64.rpm
abattis-cantarell-fonts-0.0.16-3.el7.noarch.rpm
abrt-2.1.11-36.el7.centos.x86_64.rpm
abrt-addon-ccpp-2.1.11-36.el7.centos.x86_64.rpm

Summary     : A version of the VIM editor which includes recent enhancements
Description :
VIM (VIsual editor iMproved) is an updated and improved version of the
vi editor.  Vi was the first real screen-based editor for UNIX, and is
still very popular.  VIM improves on vi by adding new features:
multiple windows, multi-level undo, block highlighting and more.  The
vim-enhanced package contains a version of VIM with extra, recently
introduced features like Python and Perl interpreters.

Install the vim-enhanced package if you'd like to use a version of the
VIM editor which includes recently added enhancements like
interpreters for the Python and Perl scripting languages.  You'll also
need to install the vim-common package.
