Can you give us a few details?
 
e.g. 
>dim(yourData)
>class(yourData)
>colnames(yourData)
 
and then the lines of code you are trying to perform knn.

Subject: [BioC] classifier using R



I' trying to write a classifier usisn R
  
    I have microarray data(.xls), i saved the data as   .txt, and import them in R with read.table()
    I  first tried to calcute knn: but i always receive the failure: Data have  differents length, when i check their Length there are same.
    
     How kann i calculate one of these classifiers sing   R:
    knn- classifier
    Bayes-classifer
    Hidden Markov Modell
    Neural net
    
    Thanks for your help
