Produces ggplot2-based Venn plots for 2, 3 or 4 sets. A Venn diagram shows all possible logical relationships between several sets of data.
venn_plot( ..., names = NULL, show_elements = FALSE, show_sets = FALSE, fill = ggplot_color(4), alpha = 0.5, stroke_color = "white", stroke_alpha = 1, stroke_size = 1, stroke_linetype = "solid", name_color = "black", name_size = 6, text_color = "black", text_size = 4, label_sep = "," )
... | A list or a comma-separated list of vectors in the same class. If
vector contains duplicates they will be discarded. If the list doesn't have
names the sets will be named as |
---|---|
names | By default, the names of the sets are set as the names of the
objects in |
show_elements | Show set elements instead of count. Defaults to |
show_sets | Show set names instead of count. Defaults to |
fill | Filling colors in circles. Defaults to the default ggplot2 color palette. A vector of length 1 will be recycled. |
alpha | Transparency for filling circles. Defaults to |
stroke_color | Stroke color for drawing circles. |
stroke_alpha | Transparency for drawing circles. |
stroke_size | Stroke size for drawing circles. |
stroke_linetype | Line type for drawing circles. Defaults to |
name_color | Text color for set names. Defaults to |
name_size | Text size for set names. |
text_color | Text color for intersect contents. |
text_size | Text size for intersect contents. |
label_sep | The separator for labs when |
A ggplot object.
