Find all peaks in density along with their indices
1 |
obj |
a 'FlowFrame', 'GatingHierarchy', 'CellPopulation' a density object or a numeric vector of density. |
channel |
a channel's name or its corresponding index. If the input is numeric vector, channel is NA. |
tinypeak.removal |
A number in [0,1] to exclude/include tiny peaks in density distribution. Default is 1/25. |
adjust.dens |
The smoothness of density in [0,Inf] to be used in density(.). The default value is 1 and should not be changed unless necessary |
node |
Chareacter for the parent population if passing GatingHierarchy object. |
verbose |
If TRUE, printing warnings. |
twin.factor |
If smaller than 1, peaks that are of greater than hieght as the maximum peak*twin.factor will be removed. |
... |
Arguments passed to smoothSpline function, spar is 0.4. |
a list, including peaks, their corresponding indices and height.
