system() indeed would be the answer, but it does not solve my problem
because of some inconsistencies in WindowsXP.
I will explain the story, because perhaps it can help somebody else to
avoid wasting time.

1. From Fisher's paper in 1987, it seems that Cobweb only deals with nominal
data. In R Weka
The problem is that the first column is probably a factor and you are
trying to assign a value that is not already a 'level' in the factor.
One way is to read the data with as.is=TRUE to keep it as character,
replace the NAs and then convert back to factors if you want to:

As usual, your reply was very helpful (although I did not directly apply
