title: Error in xj[i] : invalid subscript type 'list'
body: <p>I tried to split the data(bank) into training data and test data. But I somehow got an error below.How can I solve this problem?</p>
  
  <pre><code>train = bank[1:100, ]
  test = bank[!train,]
  Status.test =Status[!train]
  glm.fit=glm(Status~Length+Right+Bottom+Top+Diagonal,data=bank,family=binomial,subset=train)
  
  #Error in xj[i] : invalid subscript type 'list'
  
  glm.probs=predict(glm.fit,test,type="response") 
  glm.pred=rep("genuine",100)  
  glm.pred[glm.probs&gt;.5]="counterfeit"
  table(glm.pred,test)##classification on training data
  
  #Error in table(glm.pred, test) : all arguments must have the same length
  </code></pre>
