centos6.5 安装和卸载R
在centos6.5上采用非编译的方式安装R的步骤：
su -c 'rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm'
sudo yum update
sudo yum install R卸载的方法：
yum list installed | grep R
R.x86_64 2.15.2-1.el5 installed
R-core.x86_64 2.15.2-1.el5 installed
R-devel.x86_64 2.15.2-1.el5 installed
yum remove R.x86_64
yum remove R-core.x86_64这样就能把通过非编译的安装的R完全卸载干净
采用编译的方式安装R包的方式如下，在编译R之前，需要通过yum安装以下几个程序：
#yum install gcc-gfortran #否则报”configure: error: No F77 compiler found”错误
#yum install gcc gcc-c++ #否则报”configure: error: C++ preprocessor “/lib/cpp” fails sanity check”错误
#yum install readline-devel #否则报”–with-readline=yes (default) and headers/libs are not available”错误
#yum install libXt-devel #否则报”configure: error: –with-x=yes (default) and X11 headers/libs are not available”错误这里写代码片然后再编译安装
#cd
#wget http://ftp.ctex.org/mirrors/CRAN/src/base/R-2/R-2.13.1.tar.gz
#tar zxvf R-2.13.1.tar.gz
#cd R-2.13.1
#./configure
#make
#make install安装之后，如果普通用户无法打开R的话，就得在R的安装的路径下边，找到R的bin的目录，然后改变执行的权限
chmod 777 /usr/lib64/R/bin参考网页：
