Hi Petr and Eric, Thanks for your comments.
To plot a vertical line, using "lines(0)" does not work, but lines(c(-1,0),c(0,1)) does the work in my simple test example. I just interpreted the ?lines documentation wrong. So the "lines" command does work on my pc. Off course "abline(v=0)" will also do the job in this specific example...
