在Windows上设置Java R接口(JRI)
我遵循了网络上的指南,并查看了有关stackoverflow的问题,但我仍然无法在Windows上设置JRI 以下是我采取的步骤: 1) 安装R 2) 在R中执行在Windows上设置Java R接口(JRI),java,r,rjava,jri,Java,R,Rjava,Jri,我遵循了网络上的指南,并查看了有关stackoverflow的问题,但我仍然无法在Windows上设置JRI 以下是我采取的步骤: 1) 安装R 2) 在R中执行install.packages(“rJava”)以安装rJava 3) 创建一个带有值的R\u HOME系统变量C:\Program Files\R\R-3.1.2 4) 将以下内容添加到我的PATH变量中:C:\ProgramFiles\R\R-3.1.2\bin\x64;C:\Users\USERNAME\Documents\R\
install.packages(“rJava”)
以安装rJava
3) 创建一个带有值的R\u HOME
系统变量C:\Program Files\R\R-3.1.2
4) 将以下内容添加到我的PATH
变量中:C:\ProgramFiles\R\R-3.1.2\bin\x64;C:\Users\USERNAME\Documents\R\win library\3.1\rJava\jri\x64
5) 将JRI.jar(位于C:\Users\USERNAME\Documents\R\win library\3.1\rJava\JRI
)添加为IntelliJ中的依赖项
6) 将IntelliJ中的VM选项设置为-Djava.library.path=C:\Users\USERNAME\Documents\R\win library\3.1\rJava\jri\x64
7) 启动R并执行库(“rJava”)
8) 运行我的程序来测试是否一切都设置好了

Cannot find JRI native library!
Please make sure that the JRI native library is in a directory listed in java.library.path.

如果删除VM选项,因此未指定java.library.path,则会出现以下错误:

找不到JRI本机库!
请确保JRI本机库位于java.library.path中列出的目录中。

您如何实例化Rengine
应该是这样的:
Rengine-Rengine=new-Rengine(args,false,null)代码>
其中,args可能来自main方法
让我知道这是否有效 我最新(2018年)的目标是:-
export R_HOME=$(R RHOME)
然后编译这个:-
String[] enginargs = {"--no-save"};
REngine engine = org.rosuda.REngine.JRI.JRIEngine.createEngine(enginargs, null, false);
try {
engine.parseAndEval("print(\"Hello from R\");");
}
catch(Exception e ) {
System.err.println("OOps:-" + e.getMessage());
}
finally {
engine.close();
}
然后在运行java时,将LD_LIBRARY_路径设置为enclude JRI
或者设置-Djava.library.path例如
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib/R/site-library/rJava/jri/
或
