Elongated Gaussian Ellipsoid

Description

Elongated gaussian data from "How to Use t-SNE Effectively".

Usage

long_gaussian_data(n, dim, color = NULL)

Arguments

n	Number of points.
dim	Dimension of the gaussian.
color	Color to assign to the data points.

Details

Creates a randomly-sampled gaussian dataset of the specified dimension, with standard deviation following the harmonic series: the first column has standard deviation 1, the second 1/2, the third 1/3 and so on.

Value

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