R: Plot a hydrograph

hydrograph

R Documentation

Plot a hydrograph

Description

Creates a hydrograph with one or two streamflow data sets, and can include a precipitation hyetograph.

Usage

hydrograph(input = matrix(ncol = 2, nrow = 2), streamflow = input[, 2],
 timeSeries = input[, 1], streamflow2 = NULL, precip = NULL, begin = 1,
 endindex = length(streamflow), P.units = "", S.units = "",
 S1.col = "black", S2.col = "red", stream.label = "Streamflow",
 streamflow3 = NULL, streamflow4 = NULL, precip2 = NULL)

Arguments

`input`	This is a data frame with at least two columns of data First column: Must be a time/date series Second column: If including precip, precip. Otherwise, streamflow - AND do not include any other columns Third column: (Only include if precip is in the second column) First streamflow dataset Forth column: (optional) Second streamflow dataset
`streamflow`	vector of streamflow values - not necessary if using "input"
`timeSeries`	vector of time or date values - not necessary if using "input"
`streamflow2`	optional vector of streamflow values - not necessary if using "input"
`precip`	vector of precipitation values - not necessary if using "input"
`begin`	If you don't want to graph the whole data set, include the index where you would like to start
`endindex`	If you don't want to graph the whole dataset, include the index where you would like to end
`P.units`	Precipitation units (character)
`S.units`	Streamflow units (character). Users who have volumetric flow will have the superscript correctly formatted if they enter "m3s" or "ft3s"
`S1.col`	color of the line representing streamflow
`S2.col`	color of the line representing second streamflow data
`stream.label`	character string - Label for vertical axis
`streamflow3`	optional vector of additional streamflow values
`streamflow4`	optional vector of additional streamflow values
`precip2`	optional vector of a second precip gage data if you are interested in comparing precip inputs

Warning

The date series should be continuous and evenly spaced. If not, the dates will not line up accurately on the x-axis.

Note

This function can now take NA values. If you chose to use the input argument but are not including precipitation, input must only have two columns - you will need to add the second streamflow dataset using the "streamflow2" argument.
