fdplot: Plots Flow Duration Curve
In tmdl: Flow and Load Duration Curve plots for TMDL

Description Usage Arguments See Also Examples

This function produces "trellis" object with FDC given prepared flow and pollutant data.

1 2	fdplot (data, names =list(), values = FALSE, type = "l", scales = list(), xlab = "Flow Duration Interval (%)", ylab, intervals = fi, ...)

`data`	Typically result of `rankflow`, a `data.frame` with columns "Q" & "exc". Those can be overriden using `names`
`names`	List that can specify custom column names in data frame `data` for `Q` and `exc`
`values`	Show flow rate at intervals boundaries

See xyplot for these

`type`
`scales`
`xlab`
`ylab`
`...`
`intervals`	Non-standard flow intervals definitions (currently broken)

rankflow.

data(flow)
data(pol)
ranked <- rankflow(flow, pol, names = list(date="Date", Q="cfs"))
options(digits=4) # can limit number of digits on plot value labels
fdplot(ranked, names=list(Q="cfs"), values=TRUE)
