plotFour: Makes four graphs of streamflow statistics on a single page

In EGRET: Exploration and Graphics for RivEr Trends

Makes four graphs of streamflow statistics on a single page

Description

Part of the flowHistory system. The four statistics are 1-day maximum, annual mean, annual 7-day minimum, and the running standard deviation of the log daily discharge values.

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 Daily dataframe with the daily flow data, and an INFO dataframe with metadata. Each graph shows a loess smooth of the data that are plotted.

Usage

plotFour(eList, yearStart = NA, yearEnd = NA, printTitle = TRUE,
  runoff = FALSE, qUnit = 1, window = 15, cex = 0.8, cex.axis = 1.2,
  cex.main = 1.2, col = "black", lwd = 1, ...)

Arguments

eList	named list with at least Daily and INFO dataframes
yearStart	A numeric value for year in which the graph should start, default is NA, which indicates that the graph should start with first annual value
yearEnd	A numeric value for year in which the graph should end, default is NA, which indicates that the graph should end with last annual value
printTitle	logical variable, if TRUE title is printed, if FALSE title is not printed, default is TRUE
runoff	logical variable, if TRUE the streamflow data are converted to runoff values in mm/day
qUnit	object of qUnit class printqUnitCheatSheet, or numeric represented the short code, or character representing the descriptive name.
window	numeric which is the full width, in years, of the time window over which the standard deviation is computed, default = 15
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. Default is 1.
...	arbitrary graphical parameters that will be passed to genericEGRETDotPlot function (see ?par for options)
