No examples for the filter/mutate/select functions

[david-barnett]

None of the functions in handlers.R have examples on their help pages.

You might like to combine a few of the related help pages together, e.g. all the filtering functions,

But I definitely think you need to give at least one working example for each function, or otherwise direct users who look in the help where to find examples elsewhere.

This is actually a more general problem. Most (?) functions don't have examples on their help pages.

I feel you need to add examples on help pages, or direct to specific places in online documentation
