setVennOpts: Set graphical parameters of an nVenn object diagram.

In nVennR2: An Interface to 'nVenn2'

Set graphical parameters of an nVenn object diagram.

Description

The function returns an object whose parameters will change the way the diagram is plotted.

Usage

setVennOpts(
  nVennObj,
  opacity = 0.4,
  fontSize = 12,
  lineWidth = 1,
  palette = 0,
  showRegions = TRUE,
  showWeights = TRUE,
  plot = TRUE
)

Arguments

nVennObj	nVenn object generated with nVennDiagram().
opacity	Opacity of sets, between 0 (completely transparent) and 1 (completely opaque). Defaults to 0.4.
fontSize	Size of the font for the numbers of elements (weights) in each region. It also indirectly controls the font sizes of the region descriptions, if shown (showRegions=TRUE). Defaults to 10.
lineWidth	Width of the lines defining each set. The value will be rounded to the closest integer. Defaults to 1.
palette	Color palette to use to fill the sets. Integer from 0 to 3. Defaults to 0.
showRegions	If true (default), show region descriptions.
showWeights	If true (default), show number of elements in each region.
plot	If true (default), plots the diagram after the operation.

Value

nVennObj with graphical options set.

Examples

myv <- nVennDiagram(exampledf)
myv <- setVennOpts(myv, showRegions=FALSE, opacity=0.2, lineWidth=2)
