geolm {fastR2}

Geometric representation of linear model

Description

geolm create a graphical representation of the fit of a linear model.

Usage

geolm(formula, data = parent.env(), type = "xz", version = 1, plot = TRUE, ...)

to2d(x, y, z, type = NULL, xas = c(0.4, -0.3), yas = c(1, 0), zas = c(0, 1))

Arguments

formula

a formula as used in lm.

data

a data frame as in lm.

type

character: indicating the type of projection to use to collapse multi-dimensional data space into two dimensions of the display.

version

an integer (currently 1 or 2). Which version of the plot to display.

plot

a logical: should the plot be displayed?

...

other arguments passed to lm

x, y, z

numeric.

xas, yas, zas

numeric vector of length 2 indicating the projection of c(1,0,0), c(0,1,0), and c(0,0,1).
