boxQTwice: Two box plots side-by-side, discharge on sample days, and discharge on all days

Description

This function is used to compare the distribution of discharges in the sample data set and the discharges in the full daily data set. Note that discharge is plotted on a logarithmic axis. The data is logged before the statistics are performed to determine the output of the boxplot. 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. Although there are a lot of optional arguments to this function, most are set to a logical default.

Usage

boxQTwice(eList, printTitle = TRUE, qUnit = 2, cex = 0.8,
  cex.main = 1.1, logScale = TRUE, cex.axis = 1.1, tcl = 0.5, las = 1,
  tinyPlot = FALSE, customPar = FALSE, ...)

Arguments

eList

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

printTitle

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

qUnit

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

cex

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

cex.main

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

logScale

logical if TRUE y plotted in log axis. Defaults to TRUE.

cex.axis

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

tcl

number defaults to 0.5, specifies length of tick marks as fraction of height of a line of text

las

numeric in {0,1,2,3}; the style of axis labels, see ?par

tinyPlot

logical variable, if TRUE plot is designed to be plotted small as part of a multi-plot figure, default is FALSE.

customPar

logical defaults to FALSE. If TRUE, par() should be set by user before calling this function

...

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