Draw a subsample that preserves sparse regions of marker space

Usage

draw_subsample_rare(gated_idx, X, n_take, seed = 1L, k = 20L)

Arguments

gated_idx

Integer indices of gated cells.

X

feature matrix for those cells, in the same row order

n_take

Number of cells to draw.

seed

Random seed. The stream is restored afterwards.

k

neighbour rank for density_weights()

Value

list(idx = drawn indices, weight = sampling weight per drawn cell)
