gen_centroids {quollr}

Generate centroid coordinate

Description

This function generates all possible centroids in the hexagonal grid.

Usage

gen_centroids(
  data,
  x,
  y,
  num_bins_x,
  num_bins_y,
  x_start = NA,
  y_start = NA,
  buffer_x = NA,
  buffer_y = NA,
  hex_size = NA
)

Arguments

data

A tibble or data frame.

x

The name of the column that contains values along the x-axis.

y

The name of the column that contains values along the y-axis.

num_bins_x

Number of bins along the x-axis.

num_bins_y

Number of bins along the y-axis.

x_start

Starting point along the x-axis for hexagonal binning.

y_start

Starting point along the y-axis for hexagonal binning.

buffer_x

The buffer size along the x-axis.

buffer_y

The buffer size along the y-axis.

hex_size

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

Value

A list contains hexIDs, x and y coordinates (hexID, c_x, c_y respectively) of all hexagon bin centroids.

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
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)
