Arguments

data	Data frame contains full data or summarized data.
group_key	Column used to summarize the data. 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. Default: NULL (conduct automatic selection).
label_info	Label information type, combine from group, count, ratio. For example, use "count" , "ratio" will show count and ratio, count is main label info, ratio is in brackets. Default: count.
label_split	Pattern used to split the label, support regular expression. Default: space.
label_len	The length of label text. Used when label_split is NULL. Default: 40.
label_color	Color of the label. Default: black.
label_type	Label style, chosen from circle, horizon and none (no label). Default: circle.
label_pos	Label position, chosen from in and out. Default: in.
label_gap	Gap between label and pie plot, used when label_pos is out.
label_threshold	Threshold of the ratio to determine label position (in/out pie). Default: NULL.
label_size	Size of the label. Default: 4.
border_color	Border color. Default: black.
border_size	Border thickness. Default: 1.
nudge_x	Parameter of geom_text_repel. Default: 1.
nudge_y	Parameter of geom_text_repel. Default: 1.

Value

A ggplot2 object.
