It works fine for me on Fedora 20 (and 19 before it). When I installed R, it installed into /usr/lib64/R. There exists a file: /usr/lib64/R/etc/ldpaths which is executed by the R executable script. This sets up the LD_LIBRARY_PATH to point to the Java installation on my machine. In the /usr/lib64/R/bin directory, there is a program called "javareconf". I would suggest that you run this with the -n switch, like: R CMD /usr/lib64/R/bin/javareconf -n This will show you what it _would_ do if you left off the "-n". Make sure it looks reasonable. If it does, then run the same command, without the "-n", as the "root" superuser. In my case, that would be: sudo R CMD /usr/lib64/R/bin/javareconf You need to be "root" because it update the file /usr/lib64/R/etc/ldpaths . I am fairly sure this will fix your problem. === As a possible alternative to XLConnect, have you looked at openxlsx? It appears to have the same abilities, just some different syntax. It says that it is written in C and so should be faster than XLConnect. I have tested both packages, a little, and they both seem to work well. Well, it's 22:14 hours here and I wish that I could fall asleep. We're having problems at work and I know that the "big boss" will blame us peons if the hardware isn't fixed promptly Despite the fact that we are only software people and aren't allowed to touch the hardware. Our management's minds are not using the same logic as mine does. Frustrating. -- There is nothing more pleasant than traveling and meeting new people!
