I have a pedigree file as so: X0001 BYX859 0 0 2 1 BYX859 X0001 BYX894 0 0 1 1 BYX894 X0001 BYX862 BYX894 BYX859 2 2 BYX862 X0001 BYX863 BYX894 BYX859 2 2 BYX863 X0001 BYX864 BYX894 BYX859 2 2 BYX864 X0001 BYX865 BYX894 BYX859 2 2 BYX865
And I was hoping to change all unique string values to numbers. That is: BYX859 = 1 BYX894 = 2 BYX862 = 3 BYX863 = 4 BYX864 = 5 BYX865 = 6 But only in columns 2 - 4. Essentially I would like the data to look like this: X0001 1 0 0 2 1 BYX859 X0001 2 0 0 1 1 BYX894 X0001 3 2 1 2 2 BYX862 X0001 4 2 1 2 2 BYX863 X0001 5 2 1 2 2 BYX864 X0001 6 2 1 2 2 BYX865 Is this possible with factors? Thanks!
