Description Usage Arguments Value Author(s) See Also Examples
This function computes an lcoratdiagram
object used by other functions of this package. The object is specially designed for exploratory L-moment analysis of bivariate data. The lcoratdiagram
object is a complex assembly of L-moments, L-comoments, Spearman's Rho, Kendall's Tau, and other elements. The function provides for specialized large-scale visualization of data. The core data are identified by a site variable (site
), the paired x and y values (x
, y
) for each site, and an optional grouping or classification variable (group
). The x and y data could also be either left or right censored, which are identified by indicator variable. A multi-page PDF output file (xyfile
) of the bivariate relation between x and y and corresponding plot of nonexceedance probabilities by plotting position is created. The limits of the bivariate plot (xlim
and ylim
) can be controlled as well as the axis transformation (xtrans
, ytrans
). The labels of the bivariate plot also can be set (xlab
, ylab
). The function computes the first 5 L-moments and L-comoments, therefore dataset having less than 6 values are skipped by default (n.to.next
), but the user is welcome to increase this amount. The function also supports the simulation of bivariate normal distributions by a simulation count (nsim
). These simulated values can be useful for the visualization (plotlcoratdiagram
or plotlratdiagram
) of the uncertainty of the relations between L-moment ratios and L-comoment ratios.
