title: Why do I get this error below while using the Cubist package in R?
body: <p>I have some personal dataset. So I split it into variable to predict and predictors. 
  Following is the syntax:</p>
  
  <pre><code>library(Cubist)
  str(A)
  'data.frame':   6038 obs. of  3 variables:
   $ ads_return_count : num  7 10 10 4 10 10 10 10 10 9 ...
   $ actual_cpc       : num  0.0678 0.3888 0.2947 0.0179 0.095 ...
   $ is_user_agent_bot: Factor w/ 1 level "False": 1 1 1 1 1 1 1 1 1 1 ...
  cubist(A[,c("ads_return_count","is_user_agent_bot")],A[,"actual_cpc"])
  </code></pre>
  
  <p>And I am getting the following error</p>
  
  <pre><code>cubist code called exit with value 1
  Error in strsplit(tmp, "\"")[[1]] : subscript out of bounds
  </code></pre>
  
  <p>Is there something I am missing ?</p>
