this small example textbook afløbsteknik winther et al. (2011, polyteknisk forlag, lyngby). shows desired result (tip_corrected). note first registrated tip stays same, while smoothing takes place during rainfall. there no smoothing between rainfall events. 1 assume there should 2 hours between 2 rainfall events make them individual rainfall events.
tip<-c(1,rep(0,9),2,1,2,0,0,1,rep(0,14),1) tip_corrected<-c(1,rep(0.1,9),1.1,1,2,0.333,0.333,0.333,rep(0.0667,15)) windows() plot(tip, pch = 1) points(tip_corrected, pch = 4) legend(23,2, legend = c("tip", "tip_corrected"), pch = c(1,4))
if understand you're trying do, rather doing merge ts_tip, use approx function suitable rules linearly interpolate cumulative rainfall @ regularly spaced times. rule=1:2 leaves na's in series prior first rainfall , fills values past last acc_tip time last acc_tip value shown below. remainder of code before.
## merge data time series regular time steps # ts_tip <- merge(ts, na.locf(merge(ts, acc_tip)[,2]), join="inner")[,2] # merge acc_tip ts # ts_tip[is.na(ts_tip)] <- 0 # make 0 of na # # interpolation of cumulative rainfall @ equi-spaced times using approx function ts_tip <- xts(approx(index(acc_tip), acc_tip, rule=1:2, xout=index(ts))$y, order.by=index(ts)) ts_tip[is.na(ts_tip)] <- 0 # changes na's @ start of series 0's
