`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 2) corresponding to the angle to offset the continuous colour scale by. The continuous colour scale is calculated by converting the angle to hue where 0 corresponds to red and 2 to magenta (default = 1.33).
`label_rows`	A vector of row names or numbers to label.
`arrow_length`	length of label arrow (default = 1).
`grid`	An optional grid object. If NULL this will be calculated using 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 = 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").
`axis_colour`	The colour of the grid axes and labels (default="black").
`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)
`axis_angle`	Angle for the radial axis labels in pi radians (default = 1/6).
`legend_size`	Size for the legend text (default = 20).
`...`	Optional grid parameters to pass to `polar_grid`.

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