This is an assignment to implement a KNN model to classify the animals.

I've encountered an error when trying to do the data training. see below and please help me. Many Thanks

Error in knn.cv(d, d_target, k, prob = TRUE) :

NA/NaN/Inf in foreign function call (arg 6)

In addition: Warning messages:

1: In knn.cv(d, d_target, k, prob = TRUE) : NAs introduced by coercion

2: In knn.cv(d, d_target, k, prob = TRUE) : NAs introduced by coercion

see below coding in R.

#Load Data
