geom_stats {ggcyto} | R Documentation |
This is a virtual layer and will be instanatiated as geom_label layer within ggycto.+ operator.
geom_stats( gate = NULL, ..., value = NULL, type = "percent", negated = FALSE, adjust = 0.5, location = "gate", label.padding = unit(0.05, "lines"), label.size = 0, digits = 3 )
gate |
a 'filterList' or character (represent as a population node in GatingSet) if not supplied, ggcyto then tries to parse the gate from the first geom_gate layer. |
... |
other arguments passed to geom_label layer |
value |
the pre-calculated stats value. when supplied, the stats computing is skipped. |
type |
a vector of strings to specify the stats types. can be any or multiple values of "percent", "count", "gate_name", or "MFI" (MFI is currently not supported yet). |
negated |
whether the gate needs to be negated |
adjust |
see details for |
location |
see details for |
label.padding, label.size |
arguments passed to geom_label layer |
digits |
control the stats format |
So it is dedicated for ggcyto context and thus cannot be added to ggplot object directly.
