'Ggplot' for Three Way Polar Plot

This function creates a 3-way polar plot using 'ggplot' for a three-class comparison.

radial_ggplot(
  polar,
  type = 1,
  colours = NULL,
  label_rows = NULL,
  arrow_length = 1,
  label_size = 5,
  colour_code_labels = FALSE,
  label_colour = "black",
  grid_colour = "grey80",
  grid_width = 0.7,
  axis_colour = "black",
  axis_width = 1,
  axis_title_size = 5,
  axis_label_size = 3,
  marker_alpha = 0.7,
  marker_size = 3,
  marker_outline_colour = "white",
  marker_outline_width = 0.5,
  legend_size = 20,
  ...
)

Arguments

polar	A 'volc3d' object with the p-values between groups of interest and polar coordinates created by polar_coords, deseq_polar or voom_polar.
type	Numeric value whether to use scaled (z-score) or unscaled (fold change) as magnitude. Options are 1 = z-score (default) or 2 = unscaled/fold change.
colours	A vector of colours for the non-significant points and each of the six groups.
label_rows	A vector of row names or indices to label
arrow_length	The length of label arrows
label_size	Font size of labels/annotations (default = 5).
colour_code_labels	Logical whether label annotations should be colour coded. If FALSE label_colour is used.
label_colour	Colour of annotation labels if not colour coded
grid_colour	The colour of the grid (default="grey80")
grid_width	The width of the axis lines (default=0.6)
axis_colour	The colour of the grid axes and labels (default="black")
axis_width	The width of the axis lines (default=1)
axis_title_size	Font size for axis titles (default = 5)
axis_label_size	Font size for axis labels (default = 3)
marker_alpha	The alpha parameter for markers (default = 0.7)
marker_size	Size of the markers (default = 3)
marker_outline_colour	Colour for marker outline (default = white)
marker_outline_width	Width for marker outline (default = 0.5)
legend_size	Size for the legend text (default = 20).
...	Optional parameters passed to polar_grid e.g. r_axis_ticks or axis_angle

Value

Returns a polar 'ggplot' object featuring variables on a tri-axis radial graph
