Re: [R] How to stop an R script when running JGR on a Linux/SuSE system

I wonder whether there is a more gentle way to stop an R script running on top of JGR aother than ... unplugging the power cord. there must be a bug in JGR on Lunux. Clicking the stop button should stop the script, clicking it here on my linux machine will immediately crash R together with

[R] scale subsets of grouped data in data frame

Hello, I'm trying to duplicate what's an easy process in RapidMiner. In RM, we can simply use two operators: subgroup iteration attribute value selection (Can use a regex for the attrribute name.) I can do this in R with a lot of code and manual steps. It would be really nice to

[R] Compare lm() to glm(family=poisson)

Dear R-helpers, I would like to compare the fit of two models, one of which I fit using lm() and the other using glm(family=poisson). The latter doesn't provide r-squared, so I wonder how to go about comparing these models (they have the same formula). Thanks very much, Mark Na
