Plots the flow duration curve for a given low flow object.
fdc(lfobj, year = "any", breakdays = NULL, colors = TRUE,
xnorm = FALSE, ylog = TRUE, legend = TRUE, separate = FALSE,
...)A vector of quantiles.
An object of class "lfobj"
numeric - The year for which the flow duration curve should be computed. If hyearstart != 1 the BFI is calculated for the hydrological year, any = "any" means the whole series should be taken.
A vector of break days if the BFI should be calculated for different seasons.
logical - If 'breakdays' are specified, should the different flow duration curves are
displayed in different colours?
logical - should the x-axis be normalized?
logical - The the logarithm of the y-axis?
logical - Should a legend be plotted?
logical - Should a separate plot be drawn for every season?
Graphical parameters handed to plot

If breakdays is a single day, e.g. "01/06", the start of the hydrological year is taken as the second break day. If more than two seasons are to be specified, a vector of all break days is needed.
