Hello All,
I am predicting recommendation movies.
I am passing the command line argument as userId.
Rscript example.R userId
"Rscript example.R 80"
Save and load model working perfectly.So i am facing the issue in predict in Movies.
I upload the error and code images Please review it and give me suggestion.
Thanks in Advance.
It's difficult to tell what is causing the error without knowing the input needed for your model. From what I can tell, it seems that the data frame that you are using in the predict function is not matching the format needed for the model.
Hi Francisco and Mackenzie,
I have S4 predict function.
In that function there is model,ratingmat,n=100(top 100 recommend)
So in the ratingmat[1] so it is getting output of user 1
Now i want to pass ratingmat as a commandline argument
Rscript example.R 50
so it give me user number 50 top 100 recommendation
Now issue i am facing the issue is
passing the argument is character
and ratingmat typeof is S4 so how can i pass in s4 predict function
Thanks in advance.
