getBackground {FELLA} | R Documentation

## Get compounds in the defined background

### Description

Extractor function for the compounds defined as background

### Usage

    getBackground(object)

### Arguments

`object` | FELLA.USER object

### Value

Vector of compounds in the background. If this vector is empty, all the compounds are used as background by default.

### Examples

    data(FELLA.sample)
    data(input.sample)
    input <- head(input.sample, 12)

    ## If the background is default, we see an empty vector
    ## Note that the number of iterations is really small in the example
    obj <- enrich(
    compounds = input,
    method = "diffusion",
    approx = "simulation",
    niter = 100,
    data = FELLA.sample)

    getBackground(obj)

    ## Otherwise we see the background compounds that mapped to the graph
    obj <- enrich(
    compounds = input,
    compoundsBackground = input.sample,
    method = "diffusion",
    approx = "simulation",
    niter = 100,
    data = FELLA.sample)
    getBackground(obj)
