How to adapt this piece of code but for: - gamma distribution - 3 parameter log normal
More specifically, where can I find the specification of the parameter (lmom) for pelgam() and pelln3()?
Lmom package info just gives: pelgam(lmom), lelln3(lmom), where lmom is a numeric vector containing the L-moments of the distribution or of a data sample.
# Draw an L-moment ratio diagram and add a line for the
# Weibull distribution
lmrd()
weimom <- sapply( seq(0, 0.9, by=0.01),
function(tau3) lmrwei(pelwei(c(0,1,tau3)), nmom=4) )
lmrdlines(t(weimom), col='darkgreen', lwd=2)

Thank you.
