I've used the following to get a few different line types. However, I'd be interested to 
hear from someone with expertise in creating line types that are "maximally 
distinguishable" by human eyes.

ltys = c("22", "44", "13", "1343", "73", "2262", "12223242", "F282", "F4448444", 
"224282F2", "F1")

Best wishes

Richard.

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.

Hi Werner,
If you look at lty, there is an option for defining broken line types by strings of up to 8 hexadecimal digits, e.g.

abline(h=1,lty="28f8")

gives a line like the "centerline" used in mechanical drawing.
