我正在尝试从 Rjava 文件夹中执行示例 1，我已在 netbeans 的库中安装了 JRI.jar、JAREngine.jar、REngine.jar，并且还给出了用户和系统变量的这 3 个路径:C:\Program Files\R\R-3.3.1\library\rJava\jri\i386;C:\Program Files\R\R-3.3.1\library\rJava\jri\x64;C:\Program文件\R\R-3.3.1\library\rJava\jri;
系统:32/64位R均已安装并访问。
但它向我显示错误消息:
Error:
Cannot find JRI native library!
Please make sure that the JRI native library is in a directory listed in java.library.path.
java.lang.UnsatisfiedLinkError: C:\Program Files\R\R-3.3.1\library\rJava\jri\i386\jri.dll: Can't load IA 32-bit .dll on a AMD 64-bit platform

最佳答案
问题已解决:在bat文件开头添加此命令:set R_HOME=C:\Program Files\R\R-2.15.0\; Location bat 文件 C:\Program Files\R\R-3.3.1\library\rJava\jri
