Title:  update list.join example to work correctly

when I tried to perform the `list.join` docs example 2, I got error

```
list.join(l1,l2,.["name","age"])
Error in .["name", "age"] : incorrect number of dimensions
```

I believe this should be instead

```
list.join(l1,l2,.[c("name","age")])
```
