[R] Custom ticks on x axis when dates are involved - many thanks!

[Monica Pisica]

Hi,
 
I am sorry i am sending this again, but my email was snatched over the weekend by a spam generator and i was not able to send any email out. But now things are again back to normal. Even if i wrote to those who answered my question, i would like to let the list know that i got actually 2 solutions, both correct, but the following one is amazingly clear, short and to the point. I still struggle with the concept of dates in R.
 
Thanks a lot,
 
Monica

However i would really appreciate if i can get the ticks on my x axis how i want in a much more elegant way - if possible (and if not at least in the correct way).
