@brkyvz I ran into a trouble using `sparkR` with the CSV package from the
master branch and I think this PR might be the related to the problem. If I run
`./bin/sparkR --packages com.databricks:spark-csv_2.10:1.2.0` then I get
```
Exception in thread "main" java.lang.NullPointerException

```
This seems to be happening because we pass `Some(args.repositories)` in
line 287 [1] and if the argument is not given it'll be `null` ? Should this
just be `Option(args.repositories)` ?
