On Windows, goto 'Control Panel -> System -> Advanced Settings -> Environment Variables'. 'C:\Program Files\Java\jdk1.7.0_02\jre\lib\ext'Ĭheck your system PATH settings. Make sure that the Java 'CLASSPATH' variable is set properly.įor the 64-bit version of the JDK, this is typically set to something like the following(on Windows): For 64-bit Revolution R you need to make sure that you have a 64-bit version of Java installed. Make sure that the environment variable 'JAVA_HOME' is set properly and points to a 64-bit version jof Java(JDK or SE You should check the following on Windows: Their are a number of environment variables and paths that need to be set on your system, in order for the 'rJava' package onLoad failed in loadNamespace() for 'rJava' Solution
