R語言的安裝
首先，從官網上下載3.3.2版本。

wget https://cran.r-project.org/src/base/R-3/R-3.3.2.tar.gz下載完後記得解壓，我的習慣是解壓在/usr/local下面

tar -zxvf R-3.3.2.tar.gz 然後，編譯過mysql的小夥伴肯定也知道，各種環境的安裝（gcc等等）。
mysql的各種依賴環境。

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
安裝完依賴環境後，準備建立編譯後的文件夾R
我習慣建立在usr中

mkdir /usr/local/R接下來，進入R中，準備進行安裝了。該R的安裝是通過configure進行安裝

cd /usr/local/R-3.3.2
./configure --enable-R-shlib=yes --with-tcltk --prefix=/home/hadoop/R環境配置完畢後，可以進行make和安裝了

make & make install配置I5的話 大概是15到20分鐘。

編譯安裝完畢後，進行環境配置。

vim /etc/profile
#add R env
R_HOME=/usr/local/R
PATH=$PATH:$R_HOME/bin
source /etc/profile然後直接輸入R回車就能進入R的控制臺了。

[[email protected] bin]# source /etc/profile
[[email protected] bin]# R

1，如果提示以上安裝包未安裝的話，請重新安裝。
2，缺少什麽就使用yum search 缺少的名稱，再根據相應的包來進行安裝。
3，有可能是其中的Python版本指定有問題。可能需要更新python版本或者內核。
4，沒有特別報錯，但最後出現

configure: WARNING: you cannot build info or HTML versions of the R manuals ?1
你需要安裝

yum install -y texinfo.x86_64
yum install -y texlive-pdftex-doc.noarch?1
?2
5，make的時候一直不動，然後報錯’pdflatex’ is needed to make vignettes but is missing on your system.
下載安裝yum install -y texlive
