Time-series spectral frequency analysis.
Usage
spectralFrequency(data, pollutant, ...)
Arguments
- data
data.frame holding data to be analysed,
expected to contain a timestamp data-series called
date and a measurement time-series to be analysed
identified using the pollutant argument.
- pollutant
The name of the time-series,
typically pollutant measurements, to be analysed.
- ...
extra arguments.
Value
spectralFrequency uses the show
argument to control which elements of the functions outputs
are shown but also invisibly returns a list
of all outputs which can caught using, e.g.:
sfa.mod <- spectralFrequency(data, pollutant)
Details
spectralFrequency producing a
time frequency analysis of the requested
pollutant.
Examples
spectralFrequency(aq.data, "no2")
