Hi,
You could reduce those steps by:
as.data.frame(do.call(rbind,a2))

Dear Kane,
Great and thanks for the do.call function.

One way is to put them in a list.
Does this help?
a0 <- data.frame(initial_size=sample(30,1

a0 <- data.frame(initial_size=sample(30,10),sp=gl(2,5,10),
grow=as.numeric(as.character(gl(2,5,10)))*0.5)
a2<- list()
for( i in 1:3){
a1 <- a0$initial_size+a0$grow
a2[[i]] <- cbind(sp=a0$sp,initial_size=a1+i,yr=i)
}

In line with what you are doing now, but saving the intermediate results
you could use something like this.
a3 <- a0
for( i in 1:3)
{
a1 <- a0$initial_s
