I have Document Term Matrix turned data frame with 352 observations of 1342 variables. Now when I try to run a randomforest model I get the error:
model <- randomForest(labels~ ., data = train_df, ntree = 100)
Error in model.frame.default(terms(reformulate(attributes(Terms)$term.labels)), : invalid type (special) for variable 'repeat'
I know 'repeat' is a reserve word in R, but how can I solve this issue. I cannot even change the column name in this condition and find it difficult to find a solution on net.
Help in this matter will be highly appreciated.
I have tried this but is doesnt help:
model <- randomForest(labels~ ., data = train_df, ntree = 100, `repeat` = train_df$`repeat`)
