Usage example

In langevitour: Langevin Tour

knitr::opts_chunk$set(
  collapse = TRUE,
  comment = "#>"
)

As an example we will use measurements of penguins made at Palmer Station, Antarctica.

Since the measurements are in different units, we supply an appropriate scaling.

library(langevitour)
library(palmerpenguins)

completePenguins <- na.omit(penguins[,c(1,3,4,5,6)])
completePenguins

scale <- apply(completePenguins[,-1], 2, sd)*4

langevitour(
    completePenguins[,-1], completePenguins$species, 
    scale=scale, pointSize=2, elementId="myWidget")

Things to try:

Drag labels onto the plot.

Example Clear

Turn on a guide.

PCA None

Experiment with "damping" and "heat" in the hamburger menu.

Twitchy Smooth Hot Cool Default

When only three measurements are shown, your eyes will interpret the display as 3D. Hide measurements by unchecking the checkbox on their label.

Hide bill length Show all

Some further examples have been omitted from the CRAN package due to their large size and problematic dependencies. They can be viewed on the langevitour website:
