Power Spectral Sensity
I am working with a dissolved oxygen dataset. continuous readings are taken
at 15 minute intervals and we have been recording these data at 12 stations
along the savannah river for two years now. The longest set of readings
that are continuous without interuption is 53 days. I would like to look at
the power spectral density at each of these sites (most likely one day will
be the overridding

CDF calculation from kernel density estimates for a 324X 15 matrix
...grate (f, -Inf, 25.25) # I also have to calculate cdf at 30,
33, 37 heavy precipitation days
I know I am misunderstanding the code somewhere. But not being able to
figure it out. Basically I want to calculate bandwidth for each of the 324
rows separately and then I need to calculate the kernel sensity estimate for
each of 324 rows separately and cdf for all those rows separately at 5
different data points. So I guess I have to use for loops too?
This is my 1st program in R and I am sorry if this problem sounds very
easy.
Any suggestions and help would be highly appreciated!
Thanks very much i...
