tri_bin_centroids {quollr}

Triangulate bin centroids

Description

This function triangulates the bin centroids using the x and y coordinates provided in the input data frame and returns the triangular object.

Usage

tri_bin_centroids(hex_df, x, y)

Arguments

hex_df

The data frame containing the bin centroids.

x

The name of the column that contains x coordinates of bin centroids.

y

The name of the column that contains y coordinates of bin centroids.

Value

A triangular object representing the triangulated bin centroids.

Examples

y = "UMAP2", hex_size = NA, buffer_x = NA, buffer_y = NA)
