panel.dierckx: Panel function for xyplot.dierckx

In DierckxSpline: R companion to "Curve and Surface Fitting with Splines"

Description

This is the default panel function for 'xyplot.dierckx'.

Usage

panel.dierckx(x, y, newx, newy, knots = NULL, knots.y = NULL, lty = 2,
              knot.cex = 1.5, knot.col = "red", knot.fill = "lightgray",
              ...)

Arguments

x, y	points to be plotted
newx, newy	line to be drawn
knots	a vector of x-axis position to mark as interior 'knots' of the spline.
knots.y	a vector of y-axis positions corresponding to 'knots'.
lty	line type for 'panel.xyplot'.
knot.cex	character expansion for plotted knots.
knot.col	color to use when plotting the knots
knot.fill	'fill' argument passed to 'lpoints' when plotting the knots; see lpoints.
...	other graphics parameters passed to lpoints and panel.xyplot.

Details

Creates a scatterplot of 'x' and 'y' with a line plot of 'newx' and 'newy', optionally marking the knots at 'knots' and 'knots.y'.
