The only problem is that it adds the lagged variable as follows wage2.dat year person wage lag(wage, -1) 1.1 1980 1 -0.75843997 NA 1.2 1981 1 0.27233048 -0.75843997 1.3 1982 1 -1.58335767 0.27233048 1.4 1983 1 0.36805926 -1.58335767 1.5 1984 1 -0.52312153 0.36805926 2.6 1980 2 -0.53559110 NA 2.7 1981 2 -0.94935350 -0.53559110 2.8 1982 2 0.10486688 -0.94935350 2.9 1983 2 -0.50266443 0.10486688 2.10 1984 2 0.14644024 -0.50266443 . . Is there anyway I could rename the last column wag.lag1? Thanks.
