ggplot implementation of vennDiagram from limma package. currently limited at 3 sets

Description

ggplot implementation of vennDiagram from limma package. currently limited at 3 sets

Usage

ssvFeatureVenn(object, group_names = NULL, counts_txt_size = 5,
  counts_as_labels = FALSE, show_outside_count = FALSE,
  line_width = 3, circle_colors = NULL, fill_alpha = 0.3,
  line_alpha = 1, counts_color = NULL, n_points = 200,
  return_data = FALSE)

Arguments

object

will be passed to ssvMakeMembTable for conversion to membership matrix

group_names

useful if names weren't provided or were lost in creating membership matrix

counts_txt_size

font size for count numbers

counts_as_labels

if TRUE, geom_label is used instead of geom_text. can be easier to read.

show_outside_count

if TRUE, items outside of all sets are counted outside. can be confusing.

line_width

uses size aesthetic to control line width of circles.

circle_colors

colors to use for circle line colors. Uses Dark2 set from RColorBrewer by default.

fill_alpha

alpha value to use for fill, defaults to .3.

line_alpha

numeric [0,1], alpha value for circle line

counts_color

character. single color to use for displaying counts

n_points

integer. number of points to approximate circle with. default is 200.

return_data

logical. If TRUE, return value is no longer ggplot and is instead the data used to generate that plot. Default is FALSE.

Value

ggplot venn diagram

Examples

ssvFeatureVenn(list(1:3, 2:6))
ssvFeatureVenn(CTCF_in_10a_overlaps_gr)
ssvFeatureVenn(S4Vectors::mcols(CTCF_in_10a_overlaps_gr)[,2:3])
