rqPlot: Plot of quantile regression for speed calibrations

Description

Plot of quantile regression for assessing quality of speed calibrations

Usage

rqPlot(rdepth, speed, rqFit, main="qtRegression",
       xlab="rate of depth change (m/s)", ylab="speed (m/s)",
       colramp=colorRampPalette(c("white", "darkblue")))

Arguments

speed

speed in m/s.

rdepth

numeric vector with rate of depth change.

rqFit

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

main

string; title prefix to include in ouput plot.

xlab, ylab

axis labels.

colramp

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

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.
