Hi John

I don't get an error message but a warning

> write.table(myclara$clustering,"cluster.dat",append=TRUE)
Warning message:
In write.table(myclara$clustering, "cluster.dat", append = TRUE) :
  appending column names to file
>

Here it is the output of str(myclara), it looks "strange" to me. I think
"clustering" are integers and "data" are real numbers

>str(myclara)

I can't output the two variables in two different files without any problem.
