HI, Dear community,
I am using the linear discriminant analysis to build model and make new
predictions:
> dim(train) #training data
[1] 1272 22
> dim(valid) # validation data
[1] 140 22
lda.fit <- lda(out ~ ., data=train, na.action="na.omit", CV=TRUE) # model
fitting of linear discriminant analysis on training data
> predict(lda.fit, valid) # make prediction on validation data
Error in UseMethod("predict") :
no applicable method for 'predict' applied to an object of class "list"
Can anyone help with this?
Thanks so much!
