Arguments

data	Data frame contains full data or summarized data.
group_key	Column used to summarize the data, one or two are acceptable. Default: NULL.
count_type	Data frame type, chosen from "count" and "full". "count" means summarized data and "full" means full data. Default: count.
fill_color	Colors used. When length of group_key is two, color the subgroup, otherwise the main group. Default: NULL (conduct automatic selection).
label_info	Label information type of outer pie plot, chosen from count, ratio and all (count and ratio). Default: count.
label_split	Pattern used to split the label, support regular expression. Default: NULL.
label_len	The length of label text. Used when label_split is NULL. Default: 40.
label_color	Color of the label. When length of group_key is two, this should be set to one color. Default: black.
sort	Logical value, whether to order the plot by counts. Default: TRUE.
show_tick	Logical value, whether to show the tick. Default: TRUE.
tick_break	The break of tick. Default: NULL (conduct automatic selection).
show_label	Logical value, whether to show the label. Default: TRUE.
label_sep	The separator between group and count info. Default: |.
label_gap	The gap between label and plot. Default: 0.05 (count + 0.05*count).
label_size	The size of label. Default: 4.
donut_frac	The fraction of donut. Default: 0.1 (0.1*max(count)).
donut_label	Logical value, whether to show total number in the center of the plot. Default: TRUE.
donut_label_size	The label size of center label. Default: 4.
donut_label_color	The color of center label. Default: red.
border_color	Border color. Default: black.
border_size	Border thickness. Default: 1.

Value

A ggplot2 object.
