autoplot.flowSet {ggcyto} | R Documentation

## Plot cytometry data in one or two dimension with the ggcyto package.

### Description

Overloaded autoplot methods for the cytometry data structure: flowFrame or flowSet, Gatinghierarchy, GatingSet. It plots the cytometry data with geom_histogram, geom_density or geom_hex. When autoplot a GatingSet/Gatinghierarchy, the second argument should be a gate or population node. And the dimensions(channels/markers) are deduced from the gate dimensions.

### Usage

    ## S3 method for class 'flowSet'
    autoplot(object, x, y = NULL, bins = 30, ...)

    ## S3 method for class 'ncdfFlowList'
    autoplot(object, ...)

    ## S3 method for class 'flowFrame'
    autoplot(object, x, ...)

    ## S3 method for class 'GatingSetList'
    autoplot(object, ...)

    ## S3 method for class 'GatingSet'
    autoplot(object, gate, x = NULL, y = "SSC-A",
      bins = 30, axis_inverse_trans = TRUE, ...)

    ## S3 method for class 'GatingHierarchy'
    autoplot(object, gate, y = "SSC-A",
      bool = FALSE, arrange.main = sampleNames(object), arrange = TRUE,
      merge = TRUE, projections = list(), strip.text = c("parent",
      "gate"), path = "auto", ...)

### Arguments

`object` | The data source. A core cytometry data structure. A flowFrame, flowSet, GatingSet or GatingHierarchy object
`x` | define the x dimension of the plot (not used when object is a GatingSet). When object is a flowFrame, it can be missing, which plots 1d density plot on all the channels.
`y` | define the y dimension of the plot. Default is NULL, which means 1d densityplot.
`bins` | passed to geom_hex
`...` | other arguments passed to ggplot
`gate` | the gate to be plotted
`axis_inverse_trans` | logical flag indicating whether to add axis_x_inverse_trans and axis_x_inverse_trans layers.
`bool` | whether to plot boolean gates
`arrange.main` | the main title of the arranged plots
`arrange` | whether to use arrangeGrob to put multiple plots in the same page
`merge` | wehther to merge multiple gates into the same panel when they share the same parent and projections
`projections` | a list of customized projections
`strip.text` | either "parent" (the parent population name) or "gate "(the gate name). The latter usually is used when merge is FALSE
`path` | the gating path format (passed to getNodes)

### Value

a ggcyto object

### Examples

    library(flowCore)
    data(GvHD)
    fs <- GvHD[subset(pData(GvHD), Patient %in%5:7 & Visit %in% c(5:6))[["name"]]]

    #1d- density plot
    autoplot(fs, x = "SSC-H")

    #1d- density plot on all channels
    autoplot(fs[[1]])

    #2d plot: default geom_hex plot
    autoplot(fs, x = 'FSC-H', y ='SSC-H')

    #autplot for GatingSet
    dataDir <- system.file("extdata",package="flowWorkspaceData")
    gs <- load_gs(list.files(dataDir, pattern = "gs_manual",full = TRUE))
    autoplot(gs, "CD3+")
    #display axis values in transformed scale
    autoplot(gs, "CD3+", axis_inverse_trans = FALSE)

    #autplot for GatingHierarchy
    gh <- gs[[1]]
    autoplot(gh) # by default the strip.text shows the parent population

    #To display the gate name
    #autoplot(gh , strip.text = "gate")
