tourr (version 1.1.0)

grand_tour: A grand tour path.

Description

This method generates target bases by randomly sampling on the space of all d-dimensional planes in p-space.

Usage

grand_tour(d = 2, ...)

Arguments

d

target dimensionality

...

arguments sent to the generator

Details

Usually, you will not call this function directly, but will pass it to a method that works with tour paths like animate, save_history or render.

Examples

# All animation methods use the grand tour path by default
animate_dist(flea[, 1:6])
animate_xy(flea[, 1:6])
animate_pcp(flea[, 1:6])
animate_pcp(flea[, 1:6], grand_tour(4))

# The grand tour is a function:
tour2d <- grand_tour(2)
is.function(tour2d)

# with two parameters, the previous projection and the data set
args(tour2d)
# if the previous projection is null, it will generate a starting
# basis, otherwise the argument is ignored
tour2d(NULL, mtcars)
# the data argument is just used to determine the correct dimensionality
# of the output matrix
tour2d(NULL, mtcars[, 1:2])
