EGRET (version 2.3.0)

fluxBiasMulti: Produces 8-panel plot that is useful for determining if there is a flux bias problem

Description

These plots use the jack-knife estimates from WRTDS to investigate the potential flux bias problem. It can also be used for estimates constructed by other methods (such as LOADEST) if the results are stored in a data frame organized like the Sample data frame. It allows additional label information to indicate what method is used. 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, a Daily dataframe with the daily flow data, and an INFO dataframe with metadata

Usage

fluxBiasMulti(eList, qUnit = 2, fluxUnit = 3, moreTitle = "WRTDS",
  cex = 0.7, cex.axis = 1.1, cex.main = 1.1, col = "black", lwd = 1,
  ...)

Arguments

eList

named list with at least Sample, Daily, and INFO dataframes

qUnit

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

fluxUnit

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

moreTitle

character specifying some additional information to go in figure title, typically some information about the specific estimation method used, default is no additional information

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

col

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

lwd

number line width

...

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