Cannot load rJava because cannot load a shared library

If you have read this threat and neither of the suggestions above has worked so far, then it might be worth trying one further:

• Windows 7
• R version 2.12.1 (2010-12-16) 64-bit

• Java(TM) SE Runtime Environment (build 1.6.0_23-b05), Java HotSpot(TM) 64-Bit Server VM (build 19.0-b09, mixed mode)

  JAVA_HOME=C:\Program Files\Java\jre6\bin\

  Path= ...;C:\Program Files\Java\jre6\bin\server\;C:\Program Files\R\R-2.12.1\bin\x64\

The thing that finally solved my problem was to explicitly add \server\ to the PATH variable.

System information:R version 3.0.1 (2013-05-16)Platform: x86_64-w64-mingw32/x64 (64-bit)

I encountered this same problem. I was able to solve the issue with one line of code into the command window obtained from this website.

Sys.setenv(JAVA_HOME='C:\Program Files\Java\jre7')

Note that I used this particular line because I was on a 64 bit system. See website for 32-bit example.

Following up on some of Dirk's sage advice:

• Your path should probably say C:\Program Files\Java\jre6\bin\ (remove "client").
• Your path should also have C:\Program Files\R\R-2.10.1\bin\. You don't need that explicit reference to the rJava libs. I would also then remove C:\Program Files\R from the path.
• Lastly, confirm that Java is accessible by either going to your command prompt and typing java -version, or from within R by typing system("java -version").
• If you install the SDK, then you will also want a system variable JAVA_HOME which in my case points to C:\Sun\SDK\.
