Hi,

Anyone had this problem.

I run a test Data aginst my fitted Rpart Object
  
pruned.prediction <- predict( pruned.modeltree, newdata = evaluation, type =
"prob",na.action= na.omit )
Warning message: 
'newdata' had 2019 rows but variable(s) found have 5865 rows 


My new data: evaluation has 2019 rows but the number of observation in my
rpart Object is 5865. ( This is the same number of rows in the DataSet I use
to build the rpart Object).

I had tried with explicitly removing all "NA" from DataSets but no help.


Thanks
Sandip
