rqPlot {diveMove} | R Documentation |
Plot of quantile regression for assessing quality of speed calibrations
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)
speed |
Speed in m/s. |
rddepth |
Numeric vector with rate of depth change. |
z |
A 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 |
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. |
col.line |
Color to use for the regression line. |
cex.pts |
A numerical value specifying the amount by which to enlarge the size of points. |
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.
