Examples for the R Scripting operator have errors - confirmation sought for possible solution.
The examples that come with the R scripting operator (I have 9.6.000 installed) don't always work. After a bit of investigation, it turns out that the rm_main function must return data frames and not data.table objects. So, this fragment of code from the end of the example that comes with the R script operator doesn't…

Join step in SPM for post-processing
Hi Folks, I recently ran GSP to identify frequent sequential patterns in a dataset where I would like to run some post-processing on the results. I have a strong suspicion that some of my resulting frequent sequences are nested within parent sequences (i.e., sequence <a, b, c> and sequence <b, c, d> are actually a part of…

Application of bisecting kMeans with R-extension
Dear community, I've read that RapidMiner does not include the bisecting kMeans within the functionalites so that the bisecting kMeans approach can only be applied by using an R-extension. In this regard, I found the following R-code that should apply the bisecting kMeans Clustering on the underlying data:…

Reusing results of a Loop, maybe R-lang problem
Hi there, I trained a model to predict a bid amount and a bidder based on the previous bids and bidders. I'm trying to do the following. I apply the model to the first bid (columns from 'Amount.1' to 'Amount.33') and the first bidder (columns from 'Bidder.1' to 'Bidder.33') , then shift columns by 1 ('Amount.1' to…

Logical regression comparison with R
Hi for everyone.A Little bit confused. I perform Logical regression, in RapidMiner. it’s not clear how to choose a reference and how to look at it, but I sort of figured it out with "remap binominals". Never mind. That part my output in RapidMiner: It looks pretty reliable, Point (label) my question is Surgery Yes or No,…

Partial Least Squares Algorithm
Hello, Maybe it is a silly question... But is there Partial Least Squares in Rapidminer. I use it in R and I frequently find that it outperforms more complex alg's like neural nets. I would like to use it in my rm processes, but I don't find an operator to do so. I know I can always use Execute R, but it slows down the…

Execute R
I have poked around, but it's not obvious, to me at least, what the execution path is for the Execute R operator. Can we specify the location of the path, or is the script passed as a string to something like RScript via the shell/command line?
