generalAxis: Axis generation for log discharge

In USGS-R/EGRET: Exploration and Graphics for RivEr Trends

Axis generation for log discharge

Description

Discharge axis tick generation

Usage

generalAxis(x, maxVal, minVal, units = NA, logScale = FALSE,
  tinyPlot = FALSE, padPercent = 5, concentration = TRUE, concLab = 1,
  usgsStyle = FALSE, prettyDate = TRUE)

Arguments

x	vector to create scale about
maxVal	number maximum value on returned scale
minVal	number minimum value on returned scale
units	character concentration units. Typically found in INFO$param.units.
logScale	logical whether or not to return a log scale
tinyPlot	logical
padPercent	number used to pad the max and min if not specified
concentration	logical if concentration=TRUE, labels returned as concentration units, otherwise flux units.
concLab	object of concUnit class, or numeric represented the short code, or character representing the descriptive name. By default, this argument sets concentration labels to use either Concentration or Conc (for tiny plots). Units are taken from the eList$INFO$param.units. To use any other words than "Concentration" see vignette(topic = "units", package = "EGRET").
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
prettyDate	logical use 'pretty' limits for date axis if TRUE, or force the yearStart/yearEnd as limits if FALSE

Examples

eList <- Choptank_eList
Daily <- getDaily(eList)
INFO <- getInfo(eList)
x <- Daily$Q
max <- max(x)
min <- 0
units <- INFO$param.units
generalAxis(x, max, min, units)
min <- min(x)
generalAxis(x, max, min, units, log=TRUE)
generalAxis(Daily$ConcDay, 100, 0, concLab = "concentration")
