"[SOLVED]R extension works, but wrong R version"

nandadorea

I am running RapidMiner 5.3, and I got the R extension to work. However, it keeps running in R 2.15.0, even though I have new versions.

I have the following environment variables:

CLASS_PATH: C:\Program Files\Rapid-I\RapidMiner5\jre\bin
JAVA_HOME:C:\Program Files\Rapid-I\RapidMiner5\jre\bin
PATH:C:\Users\me\Documents\R\R-2.15.2\bin\x64;C:\Program Files\Rapid-I\RapidMiner5\jre\bin
R_HOME:C:\Users\me\Documents\R\R-2.15.2
R_LIBS:C:\Users\me\Documents\R\R-2.15.2\library

and the following for rapidminer.r.native lib:
C:\Users\me\Documents\R\R-2.15.2\library\rJava\jri\x64\jri.dll

despite that, when I try to run an R script, it gives me the following:
Failed with error: 'This is R 2.15.0, package 'Rcpp' needs >= 2.15.1'

any suggestions on what I may be doing wrong?

please open a command prompt , type the following commands and post the results

R --version

echo %Path%

echo %PATH%

Even without my posting it back I think you solved my problem. My institution does not allow me to have administrator privileges, so I changed my "USER" environment variables, and I thought that would do the trick. When I typed what you suggested on the command prompt, it tells me that the R version is 2.15.0, and I can see that it's fetching the PATH as BOTH my environment variables and the system ones, rather than just the user set PATH.

I will call our IT support.

谢谢你的帮助,我很抱歉把your time with this issue that is actually on my end....
