Function to get the density of points with value TRUE in the (x,y) plot

Description

Function to get the density of points with value TRUE in the (x,y) plot

Usage

get_density(
  x,
  y,
  detection,
  rows.subset = 1:nrow(detection),
  high.resolution = FALSE
)

Arguments

x	x-axis coordinates of cells in a 2D representation (e.g. resulting from PCA or t-SNE)
y	y-axis coordinates of cells in a 2D representation
detection	A logical matrix or dgRMatrix showing which gens (rows) are detected in which cells (columns)
rows.subset	Indices of the rows of 'detection' for which to get the densities. Default: all.
high.resolution	Logical: should high resolution be used? Default is FALSE.

Value

A 3-dimensional array (dim 1: genes/rows of expression, dim 2 and 3: x and y grid points) with density data
