SubsampleSeries.R: Sub-sample a time series based on another time series and...

In freyasquires/noxpro: Processing functions for raw AQD NOx data output.

Description

A high-resolution sequence is subsampled so that its data points match that of a lower-resolution sequence. These sequences will usually be time series but don't have to be. The high-resolution sequence is binned such that the bin centres are at the points of the low-resolution data and all high resolution data within a single bin is averaged.

Usage

SubsampleSeries(x.hres, y.hres, x.lres, func = mean, testplot = FALSE)

Arguments

x.hres	Sequence or array of high-resolution x-axis data points This may be a series of POSIX datetimes If x.hres == 'test' then args are ignored and test run
y.hres	Corresponding sequence of high-resolutuon y values x.lres: Sequence of low-resolution x values. Must be some overlap between x.hres and x.lres
func	Function to apply to the aggregate command over each bin Default is mean
testplot	If True then create a plot to test data. Always happens if x.hres == 'test'. Default is FALSE

Value

y.lres Rebinned y values for each x.lres point
