This is likely something only the author or maintainer of the cirt 
package can help you with.  You can find their names in the information 
printed by

library(help=cirt)

If you need to debug it yourself, use the traceback() function to find 
where the error occurred, then get the source to the package from CRAN, 
and get to work.  Debugging existing code is one way to learn a 
language, but it's not for everyone.
