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

    # data(infercnv_annots_example)
    # data(infercnv_genes_example)
