I am trying to split my data into 5 clusters. But I am getting the following error

```
> colSums(sapply(train1,is.na))
     train_id              name item_condition_id     category_name 
            0                 0                 0                 0 
   brand_name             price          shipping  item_description 
            0                 0                 0                 0 
> train1matrix=as.matrix(train1)
> train1vector=as.vector(train1matrix)
> k=5

Error in do_one(nmeth) : NA/NaN/Inf in foreign function call (arg 1)
In addition: Warning message:

```

Can someone please help me?
Thank you in advance
