...ters to specify what statistics I would like. this could be useful, too. another small enhancement: there are four elementary data frame operations that bedevil novices, so they really should have named function wrappers: delrow( dataframe d, index=45); insrow( dataframe d, (row)vector v); delcol( dataframe d, "name"); inscol( dataframe d, (col)vector v); I looked at my R "bible" (venables&ripley), too, but here too it is not as clear as it needs to be. yes, this may be programmable, but it ain't as obvious as it should be for beginners. regards, /iaw
