R Operators don't work in 2.15.x R

andresram1

Hello,

I am facing these problems with some R Operators. The problem is related with 2.15.x versions of R. The scenario is as follow:

- R Console is working fine, there is no problem with that!
- R Operator such Linear Regression, Naive Bayes and others present some problems... I tried to run the same project under Windows 7 and Mac Lion.

Ok, here is the log I got:


Mar 6, 2013 9:00:14 AM INFO: Process //RM_Repository/tests/02-testLinearRegressionWithR starts
Mar 6, 2013 9:00:14 AM INFO: Loading initial data.
Mar 6, 2013 9:00:15 AM INFO: Linear Regression: Error en library(mlr) : there is no package called 'mlr'


The reason for this error is because the "mlr" package is not suported under 2.15.x R versions. When I tried to install such package in my R environment I get a message telling me that this package is unavailable for my R version (2.15.2).


I hope you can fix this in future versions of R operators...although this problem seems to be related to "mlr" package builders

Thanx a lot!!!

Hi,
Thanks for reporting the issue. This is due to the reason the package "mlr", that is used by Rapidminer is not available for this version of R. I have logged a bug in the mlr website for the same.
