Random Walk Data

Description

Simulation data from a random walk process, from "How to Use t-SNE Effectively".

Usage

random_walk(n, dim)

Arguments

n	Number of points to sample.
dim	Number of dimensions of the dataset.

Details

Creates a dataset where the coordinate of each point is related to the previous point by a gaussian perturbation. Points are linearly mapped from their position in the walk to a rainbow color scheme.

Value

Data frame with coordinates in the X1, X2 ... Xn columns, and color in the color column.
