[R] Set of well distinguishable line types?

[Werner Wernersen]

Hi,

I am plotting several lines into one plot and would
like them to be distinguishable in print later on as
well. Thus, my question is: Is there a larger set of
such line types available like the sets available for
colors?

Maybe somebody has already put in the work to define
some additional good looking and distinguishable line
types.

Many thanks for your help,
  Werner
