R语言使用遇到的问题
(1) R语言需要是用ODBC连接mysql数据库。需要编译RODBC
报错如下：

经查原因解决方法如下：
CC=eval `"${R_HOME}/bin/R" CMD config CC`CPP=eval `"${R_HOME}/bin/R" CMD config CPP`CFLAGS=eval `"${R_HOME}/bin/R" CMD config CFLAGS`CPPFLAGS=eval `"${R_HOME}/bin/R" CMD config CPPFLAGS`
需要用到的调试命令如下：
export R_SHARE_DIR=/usr/local/lib64/R/share
