quadGate based on flowClust::tmixFiler — gate_quad

This gating method identifies two quadrants (first, and third quadrants) by fitting the data with tmixture model. It is particually useful when the two markers are not well resolved thus the regular quadGate method based on 1d gating will not find the perfect cut points on both dimensions.

Arguments

fr	`flowFrame`
channels	`character` vector specifies two channels
K	see gate_flowclust_2d
usePrior	see gate_flowclust_2d

quantile1	`numeric` specifies the quantile level(see 'level' in flowClust) for the first quadrant (x-y+)
quantile3	`numeric` specifies the quantile level see 'level' in flowClust for third quadrant (x+y-)

plot	logical whether to plot flowClust clustering results
...	other arguments passed to flowClust

Value
