************************************************** * * * lmom package news * * * ************************************************** Version 1.6 2012 Jan 23 o In lmrd(), the framing box and the lines at x=0 and y=0 are drawn in colour 'par("fg")'. The lines for distributions "GEV" and "PE3" use less bright colours. o In lmrd(), argument 'legend.lmrd' can be a list of arguments to legend(). o In lmrd() there is a small change to the default position of the legend, ensuring that if a legend box is drawn (via the argument 'legend=list(bty="o")'), its top left corner is offset by 45 degrees from the top left corner of the plot. o Removed inappropriate WRITE statements from Fortran code. o Fixed: some minor errors in the documentation (expressions for quantile functions in help topics 'cdfgev', 'cdfglo', 'cdfgpa', and 'cdfkap'). Version 1.5 2009 Nov 16 o Quantile functions drawn by evplot() now extend across the entire x range of the plot (previously, with 'par("xaxs")' at its default value "r", gaps were left at the sides of the plot). o lmrexp(), lmrgam(), lmrgev(), lmrglo(), lmrgno(), lmrgpa(), lmrgum(), lmrkap(), lmrnor(), lmrpe3(), lmrwak(), pelp(), and pelq() now have a different specification of the default values for some of their arguments. The actual usage of the functions is unchanged. The change was made so that the help files can avoid the use of a "\synopsis" section, which was giving unintended results in R 2.10.0. Version 1.4 2009 Jul 10 o New functions lmrdpoints() and lmrdlines(), to add points or lines to an existing L-moment ratio diagram. o evplot.default() is now exported from the package namespace. Version 1.3 2009 Apr 30 o evplot() is now a generic function, with (only) a default method. (Further methods will be defined in package lmomRFA, version 2.0.) o evplot(), when argument 'qfunc' is present but 'para' is missing, no longer gives an error but instead uses default values for the parameters of the distribution, i.e. internally it calls function 'qfunc' with only one argument. evdistp() and evdistq(), when argument 'para' is missing, act similarly. o lmrd(), when 'x' is supplied but not 'y', now tries to identify L-skewness and L-kurtosis elements in 'x' by name rather than by position. o lmrd() now recognizes distribution identifiers ("GEV", etc.) in either upper or lower case. o lmrd() gains an argument 'cex', to control the size of plotted points. o lmrd(), when given an argument 'col' of length 1, will apply it to the plotted points rather than to all the lines. o samlmu() and samlmu.s() give a more direct error message when their first argument is not numeric. o Fixed: evplot() would sometimes not honour the y-axis limits supplied in 'ylim'. Specifically, if argument 'qfunc' was specified, the y-axis limits would be extended if necessary to include the range of quantile values plotted. o Fixed: lmrd() would set default y axis limits based on the values of 'x', not of 'y'. Version 1.2 2009 Mar 16 o Default parameter values for the Weibull distribution are now 'c(0,1,1)'. (The previous default, 'c(0,1,0)', used an invalid value for the third parameter.) Functions affected: cdfwei(), lmrwei(), quawei(). o Fixed: cdfgum() gave incorrect results. Version 1.1 2008 Dec 23 o New functions, for the Weibull distribution: cdfwei(), lmrwei(), pelwei(), quawei(). o New functions, for the 3-parameter lognormal distribution: cdfln3(), lmrln3(), pelln3(), qualn3(). pelln3() also permits parameter estimation for the 2-parameter lognormal distributon. o Fixed: pelp() and pelq() would fail when the name of the optimization routine (argument 'method') was also the name of an object in the global environment. Version 1.0 2008 Jul 3 o Initial release. Functions included: cdfexp cdfgam cdfgev cdfglo cdfgno cdfgpa cdfgum cdfkap cdfnor cdfpe3 cdfwak evdistp evdistq evplot evpoints lmrd lmrexp lmrgam lmrgev lmrglo lmrgno lmrgpa lmrgum lmrkap lmrnor lmrp lmrpe3 lmrq lmrwak pelexp pelgam pelgev pelglo pelgno pelgpa pelgum pelkap pelnor pelp pelpe3 pelq pelwak quaexp quagam quagev quaglo quagno quagpa quagum quakap quanor quape3 quawak samlmu samlmu.s
