Not a direct answer, but: Doing data preparation and analysis in R, I have never used (or needed) "->" Concerning scripts (not directly typed to console code): I think our instructor used to tell us, he considered "->" bad style or something alike... (it's some time ago, I might be mistaken) edit: R also allows using "=" x = 1 but 2 = y # error edit 2: x <<- 1

Draw a curved arrow around from 1 to 2 to 3 and back to 1 and note which direction this arrow goes, clockwise (cw) or counterclockwise (ccw). https://www.walgreenslistens.live/

If you are using an ActionBarActivity then you can tell Android to use the Toolbar as the ActionBar like so: Toolbar toolbar = (Toolbar) findViewById(R.id.my_awesome_toolbar); setSupportActionBar(toolbar); And then calls to getSupportActionBar().setDisplayHomeAsUpEnabled(true); getSupportActionBar().setDisplayShowHomeEnabled(true); will work. You can also use that in Fragments that are attached to ActionBarActivities you can use it like this: ((ActionBarActivity) getActivity()).getSupportActionBar().setDisplayHomeAsUpEnabled(true); ((ActionBarActivity) getActivity()).getSupportActionBar().setDisplayShowHomeEnabled(true); https://www.myccpay.bid/
