[R] Getting tick positions

[Mulholland, Tom]

?axis

where you will find

See Also:

     'axTicks' returns the axis tick locations corresponding to
     'at=NULL'; 'pretty' is more flexible for computing pretty tick
     coordinates and does _not_ depend on (nor adapt to) the coordinate
     system in use.
