Memory Buffered File / Returning summary of a linear model from RScript to RapidMiner
Hi there,
lm_mod_dyn < lm(UNITS ~ PR ,data = data)
summary (lm_mod_dyn)
{
lm_mod_dyn < lm(UNITS ~ PR ,data = data)
NewData < data.frame(summary (lm_mod_dyn) )
return(NewData)
}
Now I get a new Error :
Best regards and have a nice weekend
I am trying to load / read the results of a RScript 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

The functionsummary.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/howtosavesummarylmtoafile/30371944
If you use GLM model or Logistic Regression in RapidMiner, you can extract the coefficients into a table by "Converters" extension.
