In EGRET: Exploration and Graphics for RivEr Trends

Plot of the time series of daily concentration estimates and the sample values for the days that were sampled

Description

This plot is useful for visual examination of the ability of the WRTDS, or other model, to fit the data, seen in a time-series perspective. The graph is most useful when it covers a period of just a few years and not the complete record but a complete record can be done by repeated use over a series of segments.

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

plotConcTimeDaily(eList, yearStart = NA, yearEnd = NA, tinyPlot = FALSE,
  concMax = NA, printTitle = TRUE, plotGenConc = TRUE, cex = 0.8,
  cex.axis = 1.1, randomCensored = FALSE, cex.main = 1.1,
  customPar = FALSE, col = "black", lwd = 1, prettyDate = TRUE,
  usgsStyle = FALSE, ...)

Arguments

eList	named list with at least the Daily, Sample, and INFO dataframes
yearStart	numeric specifying the starting date (expressed as decimal years, for example 1989.0) for the plot
yearEnd	numeric specifying the ending date for the plot
tinyPlot	logical variable, if TRUE plot is designed to be short and wide, default is FALSE.
concMax	number specifying the maximum value to be used on the vertical axis, default is NA (which allows it to be set automatically by the data)
printTitle	logical variable if TRUE title is printed, if FALSE title is not printed (this is best for a multi-plot figure)
plotGenConc	logical variable. If TRUE, annual concentration points from WRTDSKalman output are plotted, if FALSE WRTDS concentration is plotted,
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
randomCensored	if TRUE plot a random value for censored data. Default is FALSE.
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.
col	color of points on plot, see ?par 'Color Specification'
lwd	number line width
prettyDate	logical use 'pretty' limits for date axis if TRUE, or force the yearStart/yearEnd as limits if FALSE
usgsStyle	logical option to use USGS style guidelines. Setting this option to TRUE does NOT guarantee USGS compliance. It will only change automatically generated labels
...	arbitrary functions sent to the generic plotting function. See ?par for details on possible parameters

Examples

eList <- Choptank_eList
# Water year:
plotConcTimeDaily(eList)
plotConcTimeDaily(eList, 
                  yearStart = 1998,
                  yearEnd = 2001,
                  plotGenConc = FALSE)
