getGate,GatingHierarchy,character-method {flowWorkspace} | R Documentation

## Return the flowCore gate definition associated with a node in a GatingHierarchy/GatingSet.

### Description

Return the flowCore gate definition object associated with a node in a `GatingHierarchy` or `GatingSet` object.

### Usage

    ## S4 method for signature 'GatingHierarchy,character'
    getGate(obj, y)

    ## S4 method for signature 'GatingSet,character'
    getGate(obj, y)

    ## S4 method for signature 'GatingSetList,character'
    getGate(obj, y)

### Arguments

`obj` | A `GatingHierrarchy` or `GatingSet`
`y` | A `character` the name or full(/partial) gating path of the node of interest.

### Value

A gate object from `flowCore`. Usually a `polygonGate`, but may be a `rectangleGate`. Boolean gates are represented by a `"BooleanGate"` S3 class. This is a list boolean gate definition that references populations in the GatingHierarchy and how they are to be combined logically. If `obj` is a `GatingSet`, assuming the trees associated with each `GatingHierarchy` are identical, then this method will return a list of gates, one for each sample in the `GatingSet` corresponding to the same population indexed by `y`.

### Examples

      ## Not run: 	#gh is a GatingHierarchy
        getGate(gh, "CD3") #return the gate for the fifth node in the tree, but fetch it by name.
        #G is a GatingSet
        getGate(G, "CD3") #return a list of gates for the fifth node in each tree
