plot method for Venn diagrams
Description
Plots the Venn diagram returned by venneuler.
Usage
## S3 method for class 'VennDiagram'
plot(x, col, col.fn = function(col) hcl(col * 360, 130, 60),
alpha = 0.3, main = NULL, edges = 200, border = NA, col.txt = 1,
cex = 1, lwd = 1, lty = 1, font = NULL, family = "", ...)
Arguments
x |
object of the class |
col |
optional, vector of colors (as accepted by the graphics
system) to use. The colors are recycled if necessary (so
passing a scalar will result in all circles having the same color).
If not specified, colors are obtained by calling |
col.fn |
function taking one argument (numeric vector of values
between 0 and 1), returning a vector of colors of the same
length. It is not used if the |
alpha |
numeric, value of the alpha channel(s) for the colors
(hence their opacity). It will override any alpha channel
information in the color specification, recycling as neeed. If set
to |
main |
passed to |
edges |
integer scalar, specifies the number of edges to use when drawing circles |
border |
color of the border for each circle (recycled) or
|
lwd |
line width used to draw borders of the circles |
lty |
line type used to draw borders of the circles |
col.txt |
passed as |
cex |
passed to |
font |
passed to |
family |
passed to |
... |
any further arguments passed to |
Value
Returns NULL invisibly.

Calculates Venn and Euler Diagram
Description
venneuler calculates a Venn diagram from a set specification.
Usage
venneuler(combinations, weights, ...)
Arguments
combinations |
This can be one of:
For convenience data frames can be passed instead of matrices and they
will be coerced using |
weights |
If |
... |
Additional arguments (currently unused). |
Value
An object of the class VennDiagram with following components:
centers |
centers of the circles (columns are |
diameters |
diameters of the circles |
colors |
colors of the circles as values between 0 and 1 |
labels |
labels of the circles |
residuals |
residuals (percentage difference between input intersection area and fitted intersection area) |
stress |
stress value for solution |
stress01 |
.01 critical value for stress based on random data |
stress05 |
.05 critical value for stress based on random data |
