In USGS-R/smwrQW: Tools for censored data analysis

Q-Q Plot

Description

Produces a quantile-quantile (q-q) or a q-normal plot: methods for "lcens" and "qw" data.

Usage

## S3 method for class 'lcens'
qqPlot(x, y, alpha = 0.4, Plot = list(name = "", what =
  "points", type = "solid", width = "standard", symbol = "circle", filled =
  TRUE, size = 0.09, color = "black"), LineRef = list(name = "", what =
  "lines", color = "black"), Line1.1 = list(name = "Line of equality", what =
  "lines", color = "gray"), yaxis.log = FALSE, yaxis.range = c(NA, NA),
  xaxis.log = FALSE, xaxis.range = c(NA, NA), ylabels = 7, xlabels = 7,
  xtitle, ytitle, caption = "", margin = c(NA, NA, NA, NA),
  Censored = list(name = "", what = "points", symbol = "circle", filled =
  FALSE, size = 0.09, color = "black"), Projected = list(name = "", what =
  "points", symbol = "plus", filled = FALSE, size = 0.09, color = "black"), ...)

## S3 method for class 'qw'
qqPlot(x, y, alpha = 0.4, Plot = list(name = "", what =
  "points", type = "solid", width = "standard", symbol = "circle", filled =
  TRUE, size = 0.09, color = "black"), LineRef = list(name = "", what =
  "lines", color = "black"), Line1.1 = list(name = "Line of equality", what =
  "lines", color = "gray"), yaxis.log = FALSE, yaxis.range = c(NA, NA),
  xaxis.log = FALSE, xaxis.range = c(NA, NA), ylabels = 7, xlabels = 7,
  xtitle, ytitle, caption = "", margin = c(NA, NA, NA, NA),
  Censored = list(name = "", what = "points", symbol = "circle", filled =
  FALSE, size = 0.09, color = "black"), Projected = list(name = "", what =
  "points", symbol = "plus", filled = FALSE, size = 0.09, color = "black"), ...)

Arguments

x	the x-axis data, or data to plot if y is missing. Must be of class "lcens," "mcens," or "qw." Missing values are permitted and removed bedfore plotting.
y	the y-axis data. Missing values are permitted and removed bedfore plotting. If missing, then produce a quantile-normal plot from the data in x.
alpha	the alpha value of the function for computing plotting positions.
Plot	control parameters of the uncensored data plot.
LineRef	control parameters of the reference line (best fit between x and y. See Details.
Line1.1	control parameters for the 1:1 line. Drawn only for q-q plot. See Details.
yaxis.log	log-transform the y axis?
yaxis.range	set the range of the y axis.
xaxis.log	log-transform the x axis?
xaxis.range	set the range of the x axis.
ylabels	set the y-axis labels. See linearPretty for details.
xlabels	set the x-axis labels. See linearPretty for details.
xtitle	the x-axis title.
ytitle	the y-axis title.
caption	the figure caption.
margin	the parameters of the margin of the plot area.
Censored	control parameters of the censored values q-normal plot.
Projected	control parameters of the projected (filled in) left-censored data q-normal plot.
...	any additional arguments required for specific methods.

Details

The argument what for either LineRef or Line1.1 may be set to "none" to suppress drawing of either line.

Value
