rqPlot: Plot of quantile regression for speed calibrations

Description

Plot of quantile regression for assessing quality of speed calibrations

Usage

rqPlot(
  rddepth,
  speed,
  z,
  contours,
  rqFit,
  main = "qtRegression",
  xlab = "rate of depth change (m/s)",
  ylab = "speed (m/s)",
  colramp = colorRampPalette(c("white", "darkblue")),
  col.line = "red",
  cex.pts = 1
)

Arguments

rddepth

numeric vector with rate of depth change.

speed

numeric vector with speed in m/s.

z

list with the bivariate kernel density estimates (1st component the x points of the mesh, 2nd the y points, and 3rd the matrix of densities).

contours

list with components: pts which should be a matrix with columns named x and y, level a number indicating the contour level the points in pts correspond to.

rqFit

object of class “rq” representing a quantile regression fit of rate of depth change on mean speed.

main

character: string with title prefix to include in ouput plot.

xlab, ylab

character vectors with axis labels.

colramp

function taking an integer n as an argument and returning n colors.

col.line

color to use for the regression line.

cex.pts

numeric: value specifying the amount by which to enlarge the size of points.

Details

The dashed line in the plot represents a reference indicating a one to one relationship between speed and rate of depth change. The other line represent the quantile regression fit.
