************************************************** * * * lmomRFA package news * * * ************************************************** Version 2.1 2009 Jul 10 o evplot.rfd() is now exported from the package namespace. o Fixed: as.regdata() would give an error when its argument 'x' was a data frame with default column names ("V1, "V2", etc.). Version 2.0 2009 Apr 30 o This version of the package aims to enable straightforward computation of all the procedures in chapters 3-6 of Hosking and Wallis (1997). To that end there are several new functions: * regavlmom() computes regional average L-moments. It is similar to reglmr() but its interface is more consistent with other functions in the package. * regfit() fits a regional frequency distribution to a regional data set. * regsimh() runs simulations to estimate the distribution of heterogeneity and goodness-of-fit measures. * regsimq() runs simulations to estimate the variability of quantile estimates from a regional frequency distribution. * regqfunc() and siteqfunc() return the regional growth curve and the quantile functions for individual sites, respectively, from a regional frequency distribution fitted by regfit(). * regquant() and sitequant() directly compute quantiles of the regional growth curve and of distributions for individual sites, respectively, from a regional frequency distribution fitted by regfit(). * regquantbounds() and sitequantbounds() compute error bounds for the regional growth curve and for quantiles at individual sites, respectively, from a regional frequency distribution fitted by regfit(). * print.rfd(), print.regsimh(), and print.regsimq() are print methods for the objects returned by regfit(), regsimh(), and regsimq(), respectively. o Class "regdata" is introduced as a standard structure for storing L-moments and other key data for the sites in a region. o New function as.regdata() coerces suitably structured data frames to class "regdata". o New function evplot.rfd() is a method for generic function evplot() in package 'lmom'. It facilitates graphical display of the results returned by regfit(), regquantbounds(), and sitequantbounds(). o regsamlmu(), with suitable values of its arguments, now returns an object of class "regdata". o Argument 'regdat' of regtst() is renamed 'regdata', and is expected to be of class "regdata" (after coercion if necessary). o The data frame supplied as argument 'regdata' of regtst() now need have only 6 rather than 7 columns; if it does, some output quantities will not be calculated. o reglmr() is deprecated; regavlmom() is the recommended replacement.
