Summary

## Instruction

So far, we've only looked at lists whose members are named, but that's not always going to be the case – members can be unnamed. Let's look at the job_role list again. This time, we'll call the list job_role_no_names for clarity.

[[1]]
[1] "Data scientist"

[[2]]
[1] 10

[[3]]
[1] "R"        "Python" "Spark"    "Cloudera" "Hive" "Impala"


Notice that we can't see any member names in this list – there's no dollar sign followed by a name. Instead, we see sequential numbers in double brackets: [[1]], [[2]], and [[3]]. These are the positions of the list's members. So [[1]] denotes the first member of the list, [[2]] the second one, and so on.
