Error: oneR() package while using dataset #8

Closed reena2018 closed 3 years ago

reena2018 commented 3 years ago

I am getting errors while using optbin() function from oneR() package on my dataset to discretize numerical data to categorical bins. Error: image Sample dataset: image

Please help me in solving this issue.

reena2018 commented 3 years ago

Is the error because of negative values in the dataset?

vonjd commented 3 years ago

Could you please provide the exact commands you are using? Thank you

reena2018 commented 3 years ago

Yes. It’s Data<- optbin(upscale)

How many instances do you have altogether? Is the last column your target?

reena2018 commented 3 years ago

Yes. Last column is the target.

The only explanation I have at the moment is that because of the excessive filtering due to missing values only one value in the target column "survives". Try optbin with na.omit = FALSE to test this.

reena2018 commented 3 years ago

Ok. I will try this. Thank you very much.
