Thank for your reply. I am using the caret package for machine learning which should be supported?

 

I understand that I have to run the entire code in PowerBI however I'm trying to figure out if it is possible to use a model that I have allready trained and npt having to retrain the model each time I want to do a prediction.

 

I have the model object stored as a .rda file. I can load that model in RStudio with load() without any problems. But when I try to do load() in PowerBI it can't find or open the model object. Also in the PowerBI R query when I try to load data from a .csv file with read_csv() it cannot find the file. I have tried placing the files both in my RStudio working directory and in the R home directory specified by PowerBI.

 

Can anyone explain why I get this error?

I solved the prolem of loading files in the script. I just had to set the working directory specifying the full path instead of relative.

 

However now I have encountered another error message:

 

We encountered an error while trying to connect.

Details: "Unable to translate bytes [E4] at index 0 from specified code page to Unicode."

 

Can anyone explain to me what this means?
