 regr2.plot R Documentation

3D plot of z against x and y, with regression plane fit and display of squared residuals.

Description

3D plot of z against x and y, with regression plane fit and display of squared residuals.

Usage

regr2.plot(x, y, z,
main.in="put a useful title here",
resid.plot=FALSE,
plot.base.plane=TRUE,
plot.back.planes=TRUE,
plot.base.points=FALSE,
eye=NULL,                   ## S-Plus
theta=0, phi=15, r=sqrt(3), ticktype="detailed", ## R
...)

Arguments

 x,y,z See persp. main.in main title for plot. resid.plot Argument to resid.squares. plot.base.plane, plot.back.planes, plot.base.points Should these items be plotted? eye S-Plus only. See persp. theta, phi, r, ticktype R only. See persp. ... Other arguments to persp.

Note

This plot is designed as a pedagogical example for introductory courses. When resid.plot=="square", then we actually see the set of squares for which the sum of their areas is minimized by the method of "least squares".
