addInteractionSupport {sevenC} | R Documentation

## Add column to `GInteractions` with overlap support.

### Description

See overlap methods in `InteractionSet` package for more details on the overlap calculations: `?overlapsAny`

### Usage

    addInteractionSupport(gi, subject, colname = "loop", ...)

### Arguments

`gi` | `GInteractions` object
`subject` | another `GInteractions` object
`colname` | name of the new annotation column in `gi`.
`...` | additional arguments passed to `overlapsAny`.

### Value

`InteractionSet` `gi` as input but with additional annotation column `colname` indicating whether each interaction is supported by `subject` or not.

### Examples

    # build example GRanges as anchors
    anchorGR <- GRanges(
     rep("chr1", 4),
     IRanges(
       c(1, 5, 20, 14),
       c(4, 8, 23, 17)
     ),
     strand = c("+", "+", "+", "-"),
     score = c(5, 4, 6, 7)
    )

    # build example GIntreaction object
    gi <- GInteractions(
     c(1, 2, 2),
     c(4, 3, 4),
     anchorGR,
     mode = "strict"
    )

    # build exapple support GInteractions object
    exampleSupport <- GInteractions(
        GRanges("chr1", IRanges(1, 4)),
        GRanges("chr1", IRanges(15, 20))
    )

    # add support
    gi <- addInteractionSupport(gi, subject = exampleSupport)

    # Use colname argument to add support to differnt metadata column name
    gi <- addInteractionSupport(gi, subject = exampleSupport, colname = "example")
