curve2d: 2D Curve Dataset.

In jlmelville/snedata: SNE Simulation Dataset Functions

2D Curve Dataset.

Description

Simulation data of a 2D polynomial curve.

Usage

curve2d()

Details

This data set is used to assess the behavior of the PaCMAP method of Wang and co-workers (2021) and some related dimensionality reduction methods, specifically the effect of initialization on what should be an "easy" dataset to embed.

Points are colored based on their distance along the curve.

Value

Data frame with 1450 rows, and 3 columns: x, y columns contain the coordinates of the points and color the RGB color.
