getting error while performing oversample operation in r

Question

I am working on a machine learning model(classification) where my dataset is imbalanced and i want to balance it by using oversample() function from 'imbalance' package in R.

Below are the codes used for oversampling where 'Final.Status' is my response variable and it's a factor data type.

training <- na.omit(training)

training.oversamp <- oversample(training,method = "SMOTE",classAttr = 'Final.Status')

But while doing it i am getting below error:

Error in dataset[, classAttr] == c : 
  comparison of these types is not implemented
In addition: Warning message:
In which(dataset[, classAttr] == c) :
  Incompatible methods ("Ops.data.frame", "Ops.factor") for "=="

Also out of curiosity can anyone brief different methods used in oversample() function and which one is commonly used.

Answer 1

I had the exact same error and my solution was to transform the data set from tibble to data.frame.

In your case it could be as follows:

training.oversamp <- oversample(as.data.frame(training),method = "SMOTE",classAttr = 'Final.Status')
