Calculates the Lmoments and Lmoment ratios from a sample of data
Value
A data.frame with one row and column headings; L1, L2, L3, L4, Lcv, LSkew, and LKurt. The first four are the Lmoments and the next three are the Lmoment ratios.
Details
Lmoments calculated according to methods outlined by Hosking & Wallis (1997): Regional Frequency Analysis and approach based on LMoments. Also in the Flood Estimation Handbook (1999), volume 3.

# Get an AMAX sample and calculate the L-moments
am_27051 <- GetAM(27051)
