Description

Plot comparison with other clustering

Usage

    "cyan", "#7FFF7F", "yellow", "#FF7F00", "red", "#7F0000")),
  ...
)

Arguments

fsom	FlowSOM object, as generated by FlowSOM
cellTypes	Array of factors indicating the celltypes
colorPalette	Color palette to use.
...	Additional arguments to pass to PlotFlowSOM

Details

Examples

# Identify the files
fcs_file <- system.file("extdata", "68983.fcs", package = "FlowSOM")
gating_file <- system.file("extdata", "gatingResult.csv", package = "FlowSOM")

# Specify the cell types of interest for assigning one label per cell
cellTypes <- c("B cells",
               "gd T cells", "CD4 T cells", "CD8 T cells",
               "NK cells", "NK T cells")
                
# Load manual labels (e.g. GetFlowJoLabels can be used to extract labels from
# an fcs file)
 
gatingResult <- as.factor(read.csv(gating_file, header = FALSE)[, 1])


# Build a FlowSOM tree
flowSOM.res <- FlowSOM(fcs_file,
                       scale = TRUE, 
                       compensate = TRUE, 
                       transform = TRUE,
                       toTransform = 8:18, 
                       colsToUse = c(9, 12, 14:18),
                       nClus = 10,
                       seed = 1)
   
 # Plot pies indicating the percentage of cell types present in the nodes
 PlotPies(flowSOM.res,
          gatingResult,
          backgroundValues = flowSOM.res$metaclustering)
