[R] Problem with loading rJava in R

[Rowe, Brian Lee Yung (Portfolio Analytics)]

Did you verify that all your apps/libraries are all 64-bit compatible?
If your dll indeed exists in the directory it complains about, I would
venture that it's a mismatch between 32-bit and 64-bit libraries (R,
rJava, Java).

HTH,
Brian

Subject: [R] Problem with loading rJava in R



Hello.

I am trying to load the rJava package in R-2.7.2 (Windows XP 64-bit
RGui)
and get the following error message even though the mentioned .dll file
is
located at the directory listed in the error message. I have tried to
uninstall and reinstall the package but that does not resolve the
problem.
Then uninstallation and re-installation of R did not resolve the issue
either. Any suggestions are appreciated. charis.
