Apologies in advance for the basic nature of my question.
I've never worked with time series, but I am, at present, dealing
with evolution in time of certain scalar quantities.
By looking at the plots, scalar quantity vs time, for several of these
quantities, I am observing a correlation of "events" happening at specific,
non-regularly spaced instants of time. The fact of observing them in all
plots, to me means that they are due to some kind of objective physical
cause.
My question is: are there well known and effective methods in time series
analysis
to extract such occurrences from multiple series? Is there any package in R
that deals
with this?
Kind regards,
J
