You could also try the following:

The wh-argument sets the coordinates for the topleft corner of the

appear. You can later add a custom legend with the legend()-function.

The difftime() function has a units argument, so it seems kind of obvious
to me to think of objects of class 'difftime' as having units. And indeed

you should think of the result of converting from difftime to

specify what

Here is an example of the trouble you can have if you do not specify the units
