resample & interpolate
How do I resample and interpolate timeseries data in R?
# irregular time points at which data was sampled t <- c(5,10,15, 25,30, 40, 50) # measurements y <- c(4.3, 1.2, 5.4, 7.6, 3.2, 1.2, 3.7) f <- approxfun(t,y, method="linear") # get interpolated values for time points 5, 20, 35, 50 f(seq(from=5,to=50,by=15)) [1] 4.3 6.5 2.2 3.7
