Arguments

dlf

List as returned by distLextreme, containing the elements dat, dleB <- distLexBoot(dlf, nbest=4, conf.lev=0.5), gof.

selection

Selection of distributions. Character vector with type as in lmom2par. DEFAULT: NULL

order

If selection is given, should legend and colors be ordered by gof anyways? DEFAULT: FALSE

add

If TRUE, plot is not called before adding lines. This lets you add lines to an existing plot. DEFAULT: FALSE

nbest

Number of distributions plotted, in order of goodness of fit. Overwritten internally if selection is given. DEFAULT: 5

log

Logarithmic x-axis? DEFAULT: FALSE

xlim

X-axis limits. DEFAULT: xlim of plotting positions

ylim

Y-lim. DEFAULT: from min to extended max

las

LabelAxisStyle to orient labels, see par. DEFAULT: 1

main

Title of plot. DEFAULT: dlf$datname

xlab

X axis label. DEFAULT: "Return Period RP [a]"

ylab

Y axis label. Please note that the ubuntu pdf viewer might be unable to display unicode superscript. DEFAULT: "Discharge HQ [m3/s]"

PPcol

Plotting Position point colors, vector of length two for Weibull and Gringorton, recycled. PP are not used for fitting distributions, but for plotting only. DEFAULT: "black"

PPpch

point characters for plotting positions after Weibull and Grongorton, respectively. NA to suppress in plot and legend. DEFAULT: c(16,3)

PPcex

Character EXpansion of plotting points. DEFAULT: 1

coldist

Color for each distribution added with lines. Recycled, if necessary. DEFAULT: rainbow2

lty

Line TYpe for plotted distributions. Is recycled to from a vector of length nbest, i.e. a value for each distribution function drawn. DEFAULT: 1

lwd

Line WiDth of distribution lines. Recycled vector of length nbest. DEFAULT: 1

pch

Point CHaracter of points added at regular intervals. NA to suppress. Recycled vector of length nbest. DEFAULT: NA

cex

if pch != NA, size of points. Recycled vector of length nbest. DEFAULT: 1

n_pch

Number of points spread evenly along the line. Recycled vector of length nbest. DEFAULT: 15

legend

Logical. Add a legend? DEFAULT: TRUE

legargs

list of arguments passed to legend except for legend, col, pch, lwd, lty. DEFAULT: NULL

quiet

Suppress notes? DEFAULT: FALSE

...

Further arguments passed to plot like yaxt="n", ...

Details

This is an auxiliary graphing function to distLextreme
