save_history: Save tour history.

In tourr: Implement tour methods in pure R code

Description

Save tour history.

Usage

save_history(data, tour_path=grand_tour(), max_bases=100, start,
    rescale=TRUE, sphere=FALSE)

Arguments

data	matrix, or data frame containing numeric columns
tour_path	tour path generator
max_bases	maximum number of new bases to generate. Some tour paths (like the guided tour) may generate less than the maximum.
start	starting projection, if you want to specify one
rescale	if true, rescale all variables to range [0,1]?
sphere	if true, sphere all variables

Details

Save a tour path so it can later be displayed in many different ways.

Examples

# You can use a saved history to replay tours with different visualisations

t1 <- save_history(flea[, 1:6], max = 3)
animate_xy(flea[, 1:6], planned_tour(t1))
##andrews_history(t1)
##andrews_history(interpolate(t1))

t1 <- save_history(flea[, 1:6], grand_tour(4), max = 3)
animate_pcp(flea[, 1:6], planned_tour(t1))
animate_scatmat(flea[, 1:6], planned_tour(t1))

t1 <- save_history(flea[, 1:6], grand_tour(1), max = 3)
animate_dist(flea[, 1:6], planned_tour(t1))

testdata <- matrix(rnorm(100*3), ncol=3)
testdata[1:50, 1] <- testdata[1:50, 1] + 10
testdata <- sphere(testdata)
t2 <- save_history(testdata, guided_tour(holes, max.tries = 100), 
max = 5, rescale=FALSE)
animate_xy(testdata, planned_tour(t2))

# Or you can use saved histories to visualise the path that the tour took.
plot(path_index(interpolate(t2), holes))
plot(path_curves(interpolate(t2)))
