make_onegrid: Generate a Single Grid Cluster in High Dimensions

In cardinalR: Collection of Data Structures

Generate a Single Grid Cluster in High Dimensions

Description

This function generates a dataset consisting of one grid-like cluster (a structured cube grid) in 2D, with optional Gaussian noise dimensions added to extend the dataset into higher dimensions.

Usage

make_onegrid(n = 500, p = 4)

Arguments

n	Integer, the number of points in the grid cluster. Must be positive. Default is 500.
p	Integer, the dimensionality of the embedding space. Must be at least 2. Default is 4.

Value

A tibble containing the generated dataset with columns:

• x1, x2, ..., xp — coordinates of the data points.

• cluster — cluster assignment (always 1 for the grid).

Examples

# Default: 500 points, 4D space (grid in 2D + 2 noise dimensions)
onegrid <- make_onegrid()
