Good morning once more. My problem of yesterday has been addressed. Having
learned a few tricks from that, I wish to ask another question in connection
with that. My data is a cosmic ray data consisting of dates and counts. When
I plot a graph of counts versus dates, the resultant signal shows a number
of maximum and minimum points. These minimum points (turning points) are of
interest to me. Reading these dates and counts off from the plot is
difficult as I am dealing with a large data. I have been looking at
turnpoints function in pastecs library but have not been able to figure out
the appropriate commands that one can use to find the minima/maxima (turning
points) or pits/peaks in a series. My data is of the form shown below where
y stands for year, m month, d day and finally count. Is there a way I could
find these minima together with the dates they occurred?
I would be indebted to those of you who will show me the way out of these
problem.
Thank you.
Best regards
Ogbos
