Hi Subhamitra,
As I said, the code I sent is an approximation to get your year labels in
about the correct places. You are welcome to improve the calculations.

182 days is about half a year, so that the first "tick" will fall around
the end of June (i.e. the middle of the year). If you specify the increment
as 226, you get one too many labels. 229 is what is known as a kludge (a
clumsy solution that works)

Yes, I mistakenly thought that the observations were the same throughout
the four files. As you know this (and I didn't) you can do a better job of
placing the year labels by changing the sequence for each of the CSV (not
Excel) files. The best method of all would be to have a date for each
observation. You could then discard all these approximations I have made to
get the plots to work.

No, the arguments of the axis function are:

axis(<side of plot>, <position of ticks>, <labels for the ticks>)

The first argument is; 1=bottom, 2=left, 3=top, 4=right. The next two
arguments must be the same length. If not, you will get an error. As you
can see, only every other tick has a label to avoid crowding. There are
ways to get more tick labels on an axis.
