UpdateNodeSize {FlowSOM} | R Documentation

## UpdateNodeSize

### Description

Update nodesize of FlowSOM object

### Usage

    UpdateNodeSize(
      fsom,
      count = NULL,
      reset = FALSE,
      transform = sqrt,
      maxNodeSize = 15,
      shift = 0,
      scale = NULL
    )

### Arguments

`fsom` | FlowSOM object, as generated by `BuildMST`
`count` | Absolute cell count of the sample
`reset` | Logical. If `TRUE`, all nodes get the same size
`transform` | Transformation function. Use e.g. square root to let counts correspond with area of node instead of radius
`maxNodeSize` | Maximum node size after rescaling. Default: 15
`shift` | Shift of the counts, defaults to 0
`scale` | Scaling of the counts, defaults to the maximum of the value minus the shift. With shift and scale set as default, the largest node will be maxNodesize and an empty node will have size 0

### Details

Add size property to the graph based on cellcount for each node

### Value

Updated FlowSOM object

### Examples

    # Read from file, build self-organizing map and minimal spanning tree
    fileName <- system.file("extdata", "68983.fcs", package="FlowSOM")
    flowSOM.res <- ReadInput(fileName, compensate=TRUE,transform=TRUE,
                            scale=TRUE)
    flowSOM.res <- BuildSOM(flowSOM.res,colsToUse=c(9,12,14:18))
    flowSOM.res <- BuildMST(flowSOM.res)

    # Give all nodes same size
    PlotStars(flowSOM.res, equalNodeSize = TRUE)

    # Node sizes relative to amount of cells assigned to the node
    PlotStars(flowSOM.res)
