gen_hex_coord {quollr}

Generate hexagonal polygon coordinates

Description

This function generates the coordinates of hexagons after passing hexagonal centroids.

Usage

gen_hex_coord(centroids_df, hex_size = NA)

Arguments

centroids_df

The dataset with all hexbin ID and centroid coordinates.

hex_size

A numeric value that initializes the radius of the outer circle surrounding the hexagon.

Value

A list contains polygon id, x and y coordinates (hex_poly_id, x, and y respectively) of hexagons.

Examples

num_bins_list <- calc_bins(data = s_curve_noise_umap_scaled, x = "UMAP1",
y = "UMAP2", hex_size = NA, buffer_x = NA, buffer_y = NA)
num_bins_x <- num_bins_list$num_x
num_bins_y <- num_bins_list$num_y
centroid_list <- gen_centroids(data = s_curve_noise_umap_scaled,
x = "UMAP1", y = "UMAP2", num_bins_x = num_bins_x,
num_bins_y = num_bins_y, x_start = NA, y_start = NA, buffer_x = NA,
buffer_y = NA, hex_size = NA)
all_centroids_df <- as.data.frame(do.call(cbind, centroid_list))
gen_hex_coord(centroids_df = all_centroids_df, hex_size = NA)
