Function to guess the gate cutoff values

Usage

Coereba_GateCutoffs(x, subset, sample.name, remove.strings, marker)

Arguments

x: A GatingSet object
subset: Gate node of interest
sample.name: The keyword where specimens name is stored
remove.strings: Values to be removed from the name
marker: Default set to NULL, otherwise a list of Fluorophores you want to gate

Value

A data.frame with estimated gate cutoffs for every marker for every specimen
