## 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])
