Memory Buffered File / Returning summary of a linear model from R-Script to RapidMiner

MPB_

Hi there,

I am trying to load / read the results of a R-Script in Rapidminer.

As a result of the code:

lm_mod_dyn <- lm(UNITS ~ PR ,data = data)

summary (lm_mod_dyn) 

RapidMiner gives back 

Memory buffered file

In this post it is said, that it is important to convert the results of a script to a dataframe, so I changed the script to:

{


lm_mod_dyn <- lm(UNITS ~ PR ,data = data)


NewData <- data.frame(summary (lm_mod_dyn) )

return(NewData)

}

Now I get a new Error :

Is there a solution for that?

Best regards and have a nice weekend

Hi @MPB_,

The function summary.lm computes and returns a list of summary statistics of the fitted linear model. How can we write a list to a data frame? You can use print(summary(model)) in R scripts and the summary will show in your "Log" view.

Another option is to add some "write" scripts in R like this https://stackoverflow.com/questions/30371516/how-to-save-summarylm-to-a-file/30371944

If you use GLM model or Logistic Regression in RapidMiner, you can extract the coefficients into a table by "Converters" extension.

Cheers,

YY
