1、Ubuntu

install.packages("rJava")

然后设置: vi /etc/environment
R_HOME=/usr/lib/R
CLASSPATH=.:/home/conan/R/i686-pc-linux-gnu-library/2.13/rJava/jri
LD_LIBRARY_PATH=/home/conan/R/i686-pc-linux-gnu-library/2.13/rJava/jri

复制
cp /home/conan/R/i686-pc-linux-gnu-library/2.13/rJava/jri/libjri.so /usr/lib

3个类包, 放到JAVA的路径下面
JRIEngine.jar
JRI.jar
REngine.jar

运行
home/conan/R/i686-pc-linux-gnu-library/2.13/rJava/jri/example/rtest.java

可以成功的启动JAVA的console控制台.实现和R的交互.
