Arguments

x

object of class flowSet.
channels

name of the channel(s) or marker(s) to be used to construct the plot. The length of channels determines the type of plot to be constructed, either a 1-D density distribution for a single channel or a 2-D scatterplot with blue-red colour scale for two channels.
axes_trans

object of class transformList or transformerList generated by estimateLogicle which was used to transform the fluorescent channels of the supplied flowFrame. This transformation object will be used internally to ensure that the axes labels of the plot are appropriately transformed. The transformation object will NOT be applied to the flowFrame internally and should be applied to the flowFrame prior to plotting.
group_by

a vector of pData variables to sort and merge samples into groups prior to plotting, set to NULL by default to prevent merging. To merge all samples set this argument to TRUE or "all".
overlay

a flowFrame, flowSet, list of flowFrames, list of flowSets or list of flowFrame lists containing populations to be overlaid onto the plot(s).
gate

gate object(s) to be added to plot. For cyto_1d_plot only gate objects of class rectangleGate in either 1 or 2 dimensions are supported. Multiple gates can be supplied either as a list or filters object.
limits

indicates whether the axes limits should be based on the "data" or "machine", set to "machine" by default to show complete axes ranges. This argument will only alter the upper axis limits, to modify the lower limits use xlim and ylim.
display

numeric [0,1] to control the percentage of events to be plotted. Specifying a value for display can substantial improve plotting speed for less powerful machines.
layout

a vector of the length 2 indicating the dimensions of the grid for plotting c(#rows, #columns).
popup

logical indicating whether the plot should be constructed in a pop-up window, set to FALSE by default. popup will open OS-specific graphic device prior to plotting. Mac users will need to install XQuartz for this functionality.
xlim

lower and upper limits of x axis (e.g. c(0,5)).
ylim

lower and upper limits of y axis (e.g. c(0,5)).
title

title to use for the plot, set to the name of the sample by default. Title can be removed by setting this argument to NA.
xlab

x axis label.
ylab

y axis label.
density_modal

logical indicating whether density should be normalised to mode and presented as a percentage for 1-D plots. Set to TRUE by default.
density_smooth

smoothing parameter passed to density to adjust kernel density for 1-D plots.
density_stack

numeric [0,1] indicating the degree of offset for 1-D density distributions with overlay, set to 0.5 by default.
density_layers

numeric indicating the number of samples to stack in each plot, set to all samples by default.
density_fill

fill colour(s) for 1-D density distributions.
density_fill_alpha

numeric [0,1] used to control 1-D density fill colour transparency, set to 1 by default for solid colours.
density_line_type

line type(s) to use for 1-D density lines, set to 1 by default to use solid lines. See lty for alternatives.
density_line_width

numeric to control line width(s) for 1-D density lines, set to 1 by default.
density_line_col

colour(s) for 1-D density lines, set to "black" by default.
point_shape

shape(s) to use for points in 2-D scatterplots, set to "." by default to maximise plotting speed. See pch for alternatives.
point_size

numeric to control the size of points in 2-D scatter plots set to 2 by default.
point_col

colour(s) to use for points in 2-D scatter plots, set to NA by default to use a blue-red density colour scale.
point_alpha

numeric [0,1] to control point colour transparency in 2-D scatter plots, set to 1 by default to use solid colours.
contour_lines

numeric indicating the number of levels to use for contour lines in 2-D scatter plots, set to 0 by default to turn off contour lines.
contour_line_type

integer [0,6] to control the line type of contour lines in 2-D scatter plots, set to 1 to draw solid lines by default. See lty for alternatives.
contour_line_width

numeric to control line width(s) for contour lines in 2-D scatter plots, set to 2 by default.
contour_line_col

colour(s) to use for contour lines in 2-D scatter plots, set to "black" by default.
