PlotLabels: PlotLabels

In saeyslab/FlowSOM: Using self-organizing maps for visualization and interpretation of cytometry data

PlotLabels

Description

Plot labels for each cluster

Usage

PlotLabels(
  fsom,
  labels,
  maxNodeSize = 0,
  textSize = 3.88,
  textColor = "black",
  ...
)

Arguments

fsom	FlowSOM object, as generated by FlowSOM
labels	A vector of labels for every node.
maxNodeSize	Determines the maximum node size. Default is 0.
textSize	Size for geom_text. Default (=3.88) is from geom_text.
textColor	Color for geom_text. Default = black.
...	Additional arguments to pass to PlotFlowSOM

Details

Plot FlowSOM grid or tree, with in each node a label. Especially useful to show metacluster numbers

Value

Nothing is returned. A plot is drawn in which each node is represented by a label.

Examples

# Read from file, build self-organizing map and minimal spanning tree
fileName <- system.file("extdata", "68983.fcs", package="FlowSOM")
ff <- flowCore::read.FCS(fileName)
ff <- flowCore::compensate(ff, flowCore::keyword(ff)[["SPILL"]])
ff <- flowCore::transform(ff,
         flowCore::transformList(colnames(flowCore::keyword(ff)[["SPILL"]]),
                                flowCore::logicleTransform()))
flowSOM.res <- FlowSOM(ff,
                       scale = TRUE,
                       colsToUse = c(9, 12, 14:18),
                       nClus = 10,
                       seed = 1)

# Plot the node IDs
PlotLabels( flowSOM.res, 
            flowSOM.res$metaclustering)
