the zoo package or any other package?
Thanks

Adjusting X-axis time scale
Dear all,
I am plotting daily data from 1950 to 2000 and I wish to have the time in
X-axis to indicate years and NOT days (i.e 1950 1951,......,2000 instead of
1,2, 3, ......).
How do I set the x-axis to show years instead of days.
