Arguments

polar

A polar object with the pvalues between groups of interest and polar coordinates. Created by polar_coords.

colours

A vector of colour names or hex triplets for each of the six groups. Default = c("green3", "cyan", "blue", "purple", "red", "gold2"). Colours are assigned in order: group1+, group1+group2+, group2+, group2+group3+, group3+, group1+group3+.

non_sig_colour

The colour for non-significant markers (default = "grey60").

colour_scale

whether to use a 'discrete' or 'continuous' colour scale (default = 'discrete').

continuous_shift

The number of radians (between 0 and 6) to offset the continuous colour scale by. This is calculated by converting the angle to a hue using hsv where 0 corresponds to the colour scale starting with red and 360 with magenta (default = 2).

label_rows

A vector of row names or numbers to label.

arrow_length

The length of label arrows (default = 50).

grid

An optional grid object. If NULL this will be calculated using the default values of polar_grid.

fc_or_zscore

Whether to use the z-score or fold change as magnitude. Options are 'zscore' (default) or 'fc'.

label_size

Font size of labels/annotations (default = 14)

colour_code_labels

Logical whether label annotations should be colour coded. If FALSE label_colour is used.

label_colour

HTML colour of annotation labels if not colour coded.

grid_colour

The colour of the grid (default="grey80").

axis_colour

The colour of the grid axes and labels (default="black").

marker_size

Size of the markers (default = 6).

marker_alpha

Opacity for the markers (default = 0.7).

marker_outline_colour

Colour for marker outline (default = white)

marker_outline_width

Width for marker outline (default = 0.5)

axis_title_size

Font size for axis titles (default = 16)

axis_label_size

Font size for axis labels (default = 10)

axis_ticks

A numerical vector of radial axis tick breaks. If NULL this will be calculated using pretty.

axis_angle

Angle in radians for the radial axis (default = 5/6).

plot_height

Plot height in px (default=700).

plot_width

Plot width in px (default=700).

...

Optional parameters to pass to polar_grid.

Value

Returns a plotly plot featuring variables on a tri-axis radial graph
