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")
