I wonder if there is a way to add a "0" to every element of a R-list at the first position.

```
mylist <- list (a = 1:5, b = 11:15)

```

I'm looking for an easy way that produces the following result:

```
mylist[[1]]

```

> 
> [1] 0 1 2 3 4 5
> 
> 
> 

```
mylist[[2]]

```

> 
> [1] 0 11 12 13 14 15
> 
> 
> 

Of course my list has much more objects than just two.
