Sorry, this is what I used :
f <- function(x) {
wage <- ts(x$wage, start = x$year[1])
idx <- seq(length = length(wage))
wages <- cbind(wage, wage.lag1 = lag(wage, -1))[idx,]
cbind(x, wages)
}
result <- do.call("rbin

The important thing is that "4" in my example below can be any
computable expression:
Thanks for the input. I wanted to avoid counting the column number.
In any case, in the script -- wage.lag1 = lag(wage, -1) seems to do the

Hi
I found an example in R to create a lagged panel data set which works
fine. The only problem is that it adds the lagged variable as follows
wage2.dat
year personwagelag(wage, -1)
1.1 1980 1 -0.75843997NA
1.2 1981 1 0.27233048 -0.7584399
