QueryStarPlot: QueryStarPlot

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

QueryStarPlot

Description

Query a certain cell type

Usage

QueryStarPlot(
  fsom,
  query,
  plot = TRUE,
  colorPalette = FlowSOM_colors,
  backgroundColors = "#CA0020",
  ...
)

Arguments

fsom	FlowSOM object, as generated by BuildMST
query	Array containing "high" or "low" (or abbreviations) for the specified column names of the FlowSOM data.
plot	If true, a plot with a gradient of scores for the nodes is shown.
colorPalette	Color palette to be used for colors for "stars", "pies" or "marker". Can be either a function or an array specifying colors.
backgroundColors	Color to use for nodes with a high score in the plot. Default is red.
...	Additional arguments to pass to PlotFlowSOM

Details

Identify nodes in the tree which resemble a certain profile of "high" or "low" marker expressions.

Value

A list, containing the ids of the selected nodes, the individual scores for all nodes and the scores for each marker for each node

Examples

   file <- system.file("extdata", "68983.fcs", package="FlowSOM")
   flowSOM.res <- FlowSOM(file, compensate = TRUE, transform = TRUE, 
                  scale = TRUE, colsToUse = c(9, 12, 14:18), nClus = 10, 
                  silent = FALSE, xdim = 7, ydim = 7)
   query <- c("CD3" = "high", #CD3
              "CD4" = "low", #TCRb
              "CD8" = "high") #CD8
   query_res <- QueryStarPlot(flowSOM.res, query, equalNodeSize = TRUE)
   
   cellTypes <- factor(rep("Unlabeled", 49), 
                       levels = c("Unlabeled", "CD8 T cells"))
   cellTypes[query_res$selected] <- "CD8 T cells"
   PlotStars(flowSOM.res,
             backgroundValues = cellTypes,
             backgroundColors = c("#FFFFFF00", "#ca0020aa"))
