Adjusts all the values in the sample, of size n, by the difference between the linearly modelled ith data point and the linearly modelled nth data point.
A numeric vector which is a linearly detrended version of x.

# Get an annual maximum (AM) sample that looks to have a significant trend AM.21025 <- GetAM(21025) # plot the resulting AM as a bar plot. Then detrend and compare with another plot plot(AM.21025$Flow, type = "h", ylab = "Discharge (m3/s)") AM.Detrend <- DeTrend(AM.21025$Flow) plot(AM.Detrend, type = "h", ylab = "Discharge (m3/s)")
