Updating Packrat dependencies

1. List all packages where updates are available using old.packages().
2. Either, update a specific package using, for example, install.packages('plotly') or all packages using update.packages().
3. Run LMSgrowth2 in the usual way and check everything is working.
4. Once confirmed, save the updates to Packrat using packrat::snapshot(snapshot.sources=F).
