Can't get a crosstable!

[Mosa]

Hi all,

I'm doing a KNN on the Employee Attrition dataset and I have installed gmodels package, but I still can't get the crosstable (see PrtSc).
This is what I did:

cl = Leaver_train[,1]
Leaver_train_pred <- knn(train = Leaver_train, test = Leaver_train, cl, k=25)
Leaver_test_pred <- knn(train = Leaver_train, test = Leaver_test, cl, k=25)
CTtrain=CrossTable(x=Leaver_train_labels,y=Leaver_train_pred, prop.chisq=FALSE)
Error in CrossTable(x = Leaver_train_labels, y = Leaver_train_pred, prop.chisq = FALSE) :
x and y must have the same length

Any one an idea how to fix this?

Thanks in advance

We need a reproducible example (reprex)

FAQ: How to do a minimal reproducible example ( reprex ) for beginners

A minimal reproducible example consists of the following items: A minimal dataset, necessary to reproduce the issue The minimal runnable code necessary to reproduce the issue, which can be run on the given dataset, and including the necessary information on the used packages. Let's quickly go over each one of these with examples: Minimal Dataset (Sample Data) You need to provide a data frame that is small enough to be (reasonably) pasted on a post, but big enough to reproduce your issue. Let's say, as an example, that you are working with the iris data frame head(iris) #> Sepal.Length Sepal.Width Petal.Length Petal.Width Species #> 1 5.1 3.5 1.4 0.…

Unfortunately this soution doesn't work on this dataset
