transform,GatingSet-method {flowWorkspace} | R Documentation

## tranform the flow data asssociated with the GatingSet

### Description

The transformation functions are saved in the GatingSet and can be retrieved by getTransformations. Currently only flowJo-type biexponential transformation(either returned by getTransformations or constructed by flowJoTrans) is supported.

### Usage

    ## S4 method for signature 'GatingSet'
    transform(`_data`, translist, ...)

    ## S4 method for signature 'GatingSetList'
    transform(`_data`, ...)

### Arguments

`_data` | `GatingSet` or `GatingSetList`
`translist` | expect a `transformList` object or a list of `transformList` objects(with names matched to sample names)
`...` | other arguments passed to 'transform' method for 'ncdfFlowSet'.(e.g. 'ncdfFile')

### Value

a `GatingSet` or `GatingSetList` object with the underling flow data transformed.

### Examples

    ## Not run:
    data(GvHD)
    fs <- GvHD[1:2]
    gs <- GatingSet(fs)

    #construct biexponential transformation function
    biexpTrans <- flowJo_biexp_trans(channelRange=4096, maxValue=262144, pos=4.5,neg=0, widthBasis=-10)

    #make a transformList object
    chnls <- c("FL1-H", "FL2-H")
    transList <- transformerList(chnls, biexpTrans)

    #add it to GatingSet
    gs_trans <- transform(gs, transList)

    ## End(Not run)
