[R] Plotting a broken line?

[Aldi Kraja]

Hi Greg,

Thank you for your response and a previous posting about Macros in R.

Thank you also to Ken Knoblouch (Ken had the same idea as Greg's and 
Peter Pikal (who proposed the use of segments function).
There is only a technical specific that when applying max function to 
find the limit of y one has to use it with

max(x$indicator, na.rm =TRUE))

It worked!!!
