Usage

1
rfa(lflist, n = 7, event = 100, dist =  c("wei","gev","ln3","gum","pe3"))

Arguments

lflist

A list of "lfobj"s

n

MAM-n is used (e.g. n=7 means MAM7)

event

A value for T, e.g. event = 100 means the 100 years extreme low flow event

dist

A vector of distribution to fit, the names are according to Hostking's in his "lmom" package. Can be an of "wei","gev","ln3","gum","pe3".

#Toy example to get some more "rivers"

# Now you can work on using Hoskings lmomRFA-package, e.g.
require(lmomRFA)
regquant(c(1/1000,1/100),toyrfa)
sitequant(1/100,toyrfa)
