Compute indices of reference value using Date class
The reference values are formed based on computations
of seq for Date class arguments.
refvalIdxByDate(t0, b, w, epochStr, epochs)
t0 |
A Date object describing the time point |
b |
Number of years to go back in time |
w |
Half width of window to include reference values for |
epochStr |
One of |
epochs |
Vector containing the epoch value of the sts/disProg object |
Using the Date class the reference values are formed as follows:
Starting from t0 go i, i= 1,...,b years back in time.
For each year, go w epochs back and include from here to
w epochs after t0.
In case of weeks we always go back to the closest Monday of this date. In case of months we also go back in time to closest 1st of month.
a vector of indices in epochs which match
