It is not clear if you are asking about the number of unique values in a column in a data frame or the number of unique rows in a data frame. If there is more than one column these answers could be different. The first is question is the easier one. Just use length(unique(mydataframe$columnOfInterest)) ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help
