EGRET (version 2.3.0)

plotFluxQ: Sample data plot: observed log flux vs log discharge

Description

Concentration and discharge data used to compute flux come from a data frame named Sample which contains the sample data. The metadata come from a data frame named INFO. Although there are a lot of optional arguments to this function, most are set to a logical default. Data come from named list, which contains a Sample dataframe with the sample data, and an INFO dataframe with metadata.

Usage

plotFluxQ(eList, qUnit = 2, logScale = TRUE, fluxUnit = 3,
  tinyPlot = FALSE, fluxMax = NA, fluxMin = NA, col = "black",
  lwd = 1, printTitle = TRUE, cex = 0.8, cex.axis = 1.1,
  cex.main = 1.1, customPar = FALSE, ...)

Arguments

eList

named list with at least the Sample and INFO dataframes

qUnit

object of qUnit class. printqUnitCheatSheet, or numeric represented the short code, or character representing the descriptive name.

logScale

logical, default TRUE, TRUE creates a log-log scale, FALSE creates an arithmatic scale.

fluxUnit

object of fluxUnit class. printFluxUnitCheatSheet, or numeric represented the short code, or character representing the descriptive name.

tinyPlot

logical variable if TRUE plot is designed to fit into a multi-plot array, default is FALSE

fluxMax

numeric specifying the maximum value to be used on the vertical axis, default is NA (which allows it to be set automatically by the data)

fluxMin

numeric specifying the minimum value to be used on the vertical axis, default is NA (which allows it to be set automatically by the data)

col

color of points on plot, see ?par 'Color Specification'

lwd

number line width

printTitle

logical variable if TRUE title is printed, if FALSE not printed (this is best for a multi-plot figure)

cex

numerical value giving the amount by which plotting symbols should be magnified

cex.axis

magnification to be used for axis annotation relative to the current setting of cex

cex.main

magnification to be used for main titles relative to the current setting of cex

customPar

logical defaults to FALSE. If TRUE, par() should be set by user before calling this function (for example, adjusting margins with par(mar=c(5,5,5,5))). If customPar FALSE, EGRET chooses the best margins depending on tinyPlot.

...

arbitrary graphical parameters that will be passed to genericEGRETDotPlot function (see ?par for options)
