R语言的安装
首先，从官网上下载3.3.2版本。
wget https://cran.r-project.org/src/base/R-3/R-3.3.2.tar.gz下载完后记得解压，我的习惯是解压在/usr/local下面
tar -zxvf R-3.3.2.tar.gz 然后，编译过mysql的小伙伴肯定也知道，各种环境的安装（gcc等等）。
mysql的各种依赖环境。
sudo yum install -y gcc
sudo yum install gcc-c++
sudo yum install gcc-gfortran
sudo yum install -y glibc-headers
sudo yum install -y libreadline6-dev gfortran
sudo yum install -y readline-devel
sudo yum install -y wget libXt-devel
sudo yum install -y fonts-chinese tcl tcl-devel tclx tk tk-devel
sudo yum install -y mesa-libGLU mesa-libGLU-devel
sudo yum install -y install bzip2-devel
sudo yum install -y install xz-devel.x86_64
sudo yum install -y install pcre-devel
sudo yum install -y install libcurl
sudo yum install -y install libcurl-devel
sudo yum install -y texinfo.x86_64
sudo yum install -y texlive-pdftex-doc.noarch
sudo yum install -y texlive
安装完依赖环境后，准备建立编译后的文件夹R
我习惯建立在usr中
mkdir /usr/local/R接下来，进入R中，准备进行安装了。该R的安装是通过configure进行安装
cd /usr/local/R-3.3.2
./configure --enable-R-shlib=yes --with-tcltk --prefix=/home/hadoop/R环境配置完毕后，可以进行make和安装了
make & make install配置I5的话 大概是15到20分钟。
编译安装完毕后，进行环境配置。
vim /etc/profile
#add R env
R_HOME=/usr/local/R
PATH=$PATH:$R_HOME/bin
source /etc/profile然后直接输入R回车就能进入R的控制台了。
[[email protected] bin]# source /etc/profile
[[email protected] bin]# R

Platform: x86_64-pc-linux-gnu (64-bit)可能的错误信息
1，如果提示以上安装包未安装的话，请重新安装。
2，缺少什么就使用yum search 缺少的名称，再根据相应的包来进行安装。
3，有可能是其中的Python版本指定有问题。可能需要更新python版本或者内核。
4，没有特别报错，但最后出现
configure: WARNING: you cannot build info or HTML versions of the R manuals ?1
你需要安装
yum install -y texinfo.x86_64
yum install -y texlive-pdftex-doc.noarch?1
?2
5，make的时候一直不动，然后报错’pdflatex’ is needed to make vignettes but is missing on your system.
下载安装yum install -y texlive
