        Data from a foster feeding experiment with rat mothers
        and litters of four different genotypes: `A', `B', `I'
        and `J'.  Rice litters were separated from their natu-
        ral mothers at birth and given to foster mothers to
        rear.

        The data frame has the following components: item{Lit-
        ter}{ The genotype of the litter } item{Mother}{ The
        genotype of the foster mother } item{Wt}{ Litter aver-
        age weight gain of the litter, in grams at age 28 days.
        (The source states that the within-litter variability
        is negligible.)  }
