```If I understand what you want correctly:

> foo1 <- list(c(10,20,30), c(11,21,31))
> foo2 <- list(c(100,200,300), c(110,210,310))
> foo3 <- list(c(1000,2000,3000), c(1100,2100,3100))
> fool <- list(foo1, foo2, foo3)
> lapply(fool, function(x) do.call('rbind', x))
[[1]]
[,1] [,2] [,3]
[1,]   10   20   30
[2,]   11   21   31

[[2]]
[,1] [,2] [,3]
[1,]  100  200  300
[2,]  110  210  310

[[3]]
[,1] [,2] [,3]
[1,] 1000 2000 3000
[2,] 1100 2100 3100
