Hello,

I got problem installing R extension in RM.

I use R 2.14 64bits and RM 5.1 64bits.
Window7

Variables set:
JAVA_HOME: C:\Program Files\Java\jre6\bin
R_HOME: C:\Program Files\R\R-2.14.0

When starting RM, I got the R extension instructions but it never worked (failed to load R library.

Somebody could help?

Thanks a lot,

Nathalie

    Hi Nathalie,

    do you see any error messages? Please check also the log view in RapidMiner. If you find any error messages, please post them here.

    Kind regards,
    Marius

    Hi there Natalie,

    I see you have 64 bit Java, if your R installation is not also 64 bit then you will get a system load error. I'm writing a Cuda plugin which needs to be 64 bit, and if my Java isn't also 64 bit I get this sort of error.

    Just a thought.

    Thanks for your answer. I got R 64bits as well as RM 64bits.

    Running the RM console, I got the arror message below. Pretty long message but maybe it could help to get the problem solved...

    Thanks a lot for your help,

    Nathalie

    Hi there,

    Looking at the error message, it looks like a path problem. Have you checked this out?
