apply_median_filtering {infercnv}

R Documentation

apply_median_filtering

Description

Apply a median filtering to the expression matrix within each tumor bounds

Usage

apply_median_filtering(
  infercnv_obj,
  window_size = 7,
  on_observations = TRUE,
  on_references = TRUE
)

Arguments

infercnv_obj	infercnv_object
window_size	Size of the window side centered on the data point to filter (default = 7).
on_observations	boolean (default=TRUE), run on observations data (tumor cells).
on_references	boolean (default=TRUE), run on references (normal cells).

Value

infercnv_obj with median filtering applied to observations
