data(caniapiscau)
cania.ts <- create.ts(caniapiscau, hyrstart = 4)
cania.ts <- drop.years(cania.ts)
cania.ts <- set.plot.titles(cania.ts, 
title.elements = c("StationID", "StnName", "StateProv"))

res1 <- pks(cania.ts)
res2 <- pks.dur(res1)
res3 <- screen.metric(res2, ylabel = "Inter-Event Duration (days)")
