DirectFiltering: DirectFiltering

In EarthSystemDiagnostics/corit: time scale dependent correlation of irregular time series

Description

direct filtering with application of the time domain filter to irregular time series at regular filter positions

Usage

DirectFiltering(X, fc, tn, appliedFilter = c("gauss", "runmean", "lowpass"),
  k = 5)

Arguments

X	time series (zoo-object)
fc	cut-off frequency
tn	output vector (time) of the filtered data
appliedFilter	time domain filter (gauss, runmean, lowpass)
k	scaling factor to define the sharpness of the lowpass

Value

filtered time series (zoo-object)

Examples

timser.irreg <- zoo(rnorm(100), order.by=sort(runif(100,min=1,max=1000)))
timser.irregSmooth <- DirectFiltering(X=timser.irreg, fc=1/50, tn=seq(from=10,to=1000,by=10), appliedFilter="lowpass", k=5)
plot(timser.irreg,type="l",col="black")
lines(timser.irregSmooth,col="limegreen",lwd=3)
