prepanel.ecdfplot.flowset {flowViz} | R Documentation |
This function creates Trellis displays of Empirical Cumulative Distribution Functions from flow cytometry data using a formula interface.

x |
a formula describing the structure of the plot and the variables to be used in the display. For the prepanel and panel functions, a vector of names for the flow frames to be used in the panel. |
frames |
environment containing frame-specific data |
channel |
expression involving names of columns in the data |
f.value |
determines the number of points used in the plot
|
... |
more arguments, usually passed on to the underlying lattice methods and the panel function. |
ref |
logical; whether to add reference lines at 0 and 1 |
groups, subscripts |
grouping variable, if specified, and subscripts
indexing which frames are being used in the panel. See
|
col, col.points, pch, cex, alpha, col.line, lty, lwd |
vector of graphical parameters that are replicated for each group |
data |
a |
xlab |
Labels for data axes, with suitable defaults taken from the formula |
panel, prepanel |
the panel and prepanel functions. |
type |
type of rendering; by default lines are drawn |
as.table |
logical; whether to draw panels from top left |
signature(x = "formula", data = "flowSet")
: plote
empirical CDF for a given channel, with one or more samples per panel
Not all standard lattice arguments will have the intended effect, but many should. For a fuller description of possible arguments and their effects, consult documentation on lattice.
