Hi Petr
I followed your suggestion and I have attached a saved txt file with the data
and the script using dput(). I hope this time will work.
But by the way your code worked as well.
Many thanks.
Kind regards,Maria

Hi
better to send us your data by copying result of dput()
Based on Jims toy data, do you want something like that?
plot(aa$sdate,aa$var1,xaxt="n")
sel <- seq(1,15, 2)
axis(1, at=axis.dates[sel], labels=format(axis.dates, "%Y")[sel])
You can easily adopt it by managing the sequention.
Cheers
Petr
