flowCore (version 1.38.2)

parameters: Obtain information about parameters for flow cytometry objects.

Description

Many different objects in flowCore are associated with one or more parameters. This includes filter, flowFrame and parameterFilter objects that all either describe or use parameters.

Usage

parameters(object, ...)

Arguments

object

Object of class filter, flowFrame or parameterFilter.

...

Further arguments that get passed on to the methods.

Value

When applied to a flowFrame object, the result is an AnnotatedDataFrame describing the parameters recorded by the cytometer. For other objects it will usually return a vector of names used by the object for its calculations.

Methods

object = "filter"

Returns for all objects that inherit from filter a vector of parameters on which a gate is defined.

object = "parameterFilter"

see above

object = "setOperationFilter"

see above

object = "filterReference"

see above

object = "flowFrame"

Returns an AnnotatedDataFrame containing detailed descriptions about the measurement parameters of the flowFrame. For flowFrame objects there also exists a replacement method.

Examples

 samp <- read.FCS(system.file("extdata","0877408774.B08", package="flowCore"))
 parameters(samp)
 print(samp@parameters@data)
