Exploring fitted models by interactively taking 2-D and 3-D sections in data space.
Interactively take 2-D and 3-D sections in data space, showing where fitted
models intersect the section, and observed data near the section according to
a distance measure. See package website
for examples.
Works on Windows, Mac OS and Linux.
Requirements:
Installation:
install.packages("condvis")
Example to get started:
library(condvis)data(mtcars)m <- lm(mpg ~ wt + hp, data = mtcars)ceplot(data = mtcars, model = m, sectionvars = "hp")
