I am using rpart() using R v. 1.3.0 under Windows 2000.

I tried to run the routine with the following command:


and it turns out with the following error message:

Error in matrix(c(rp$isplit[, 2:3], rp$dsplit), ncol = 5, dimnames = 
list(tname[rp$isplit[,  :
         length of dimnames[1] not equal to array extent

the dataset prova has been imported in R using the command read.table. 
Apparently, it seems that the file has been correctly imported.

Any help will be appreciated!

thanks in advance!
