Find low-density Hexagons

This function identifies hexagons with low density based on the mean density of their neighboring hexagons.

Usage

find_low_dens_hex(df_bin_centroids_all, bin1, df_bin_centroids_low)

Arguments

df_bin_centroids_all

The tibble that contains all hexagonal bin centroids.

bin1

Number of bins along the x-axis for hexagon binning.

df_bin_centroids_low

The tibble that contains identified low-density hexagonal bin centroids.

Value

A vector containing the IDs of hexagons to be removed after investigating their neighboring bins.

Examples

num_bins_x <- 4
df_bin_centroids <- df_bin_centroids <- s_curve_obj$s_curve_umap_model_obj$df_bin_centroids
df_bin_centroids_low <- df_bin_centroids |>
dplyr::filter(std_counts <= 0.43)
find_low_dens_hex(df_bin_centroids_all = df_bin_centroids, bin1 = num_bins_x,
df_bin_centroids_low = df_bin_centroids_low)
