Examples

# 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)")
