R.dll causing Error

I am trying to execute R code using rJava but on setting R.dll path in the environment variables causing the program to crash. The program crashes on executing any R function. I also tried to run jri example but no help.

Any solution or hint would be very helpful

Solution

  • (If your using net beans) You should show the JVM the path (JRI.dll) in the following way:

    enter image description here

    To be more specific you need to point the following :

    -Djava.library.path='C:/Users/yschellekens.INTRANET/Documents/R/win-library/3.0/rJava/jri/x64/'

    to where the JRI.dll is located, although this might not be your problem, since when i'm removing the path in Netbeans, i get the following error (which is different from yours):

    run:
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: no jri in java.library.path
