cyto_channels(x, select = NULL, exclude = NULL, ...)

Arguments

x	object of class flowFrame, flowSet, GatingHierarchy or GatingSet.
select	vector of channel names to select.

# Load in CytoExploreRData to access data
library(CytoExploreRData)

# Activation flowSet
fs <- Activation

# Activation GatingSet
gs <- GatingSet(fs)

# flowFrame
cyto_channels(fs[[1]])

# flowSet
cyto_channels(fs)

# GatingHierarchy
cyto_channels(gs[[1]])

# GatingSet - exclude FSC & SSC channels
cyto_channels(gs, exclude = c("FSC","SSC"))
