Description

It is a virtual layer and will be instanatiated as geom_label layer within ggycto.+ operator.

Usage

geom_stats(gate = NULL, ..., value = NULL, type = "percent", data_range = NULL, adjust = 0.5, label.padding = unit(0.05, "lines"), label.size = 0)

Arguments

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

can be "percent", "count" or "MFI".

data_range

the data range for each channels

adjust

adjust the position of the centroid. from 0 to 1.

label.padding,label.size

arguments passed to geom_label layer

Value

a geom_popStats layer

Details

So it is dedicated for ggcyto context and thus can't not be added to ggplot object directly.

Examples

dataDir <- system.file("extdata",package="flowWorkspaceData")
gs <- load_gs(list.files(dataDir, pattern = "gs_manual",full = TRUE))
p <- ggcyto(gs, aes(x = CD4, y = CD8), subset = "CD3+") + geom_hex(bins = 64)
p
# add gate and stats layer
p + geom_gate("CD4") + geom_stats()
