Printing Venn Diagram after calculating overlap - r

Question

I'm trying to use the calculate.overlap function within the VennDiagram package to first calculate and then print a Venn Diagram. I was able to calculate the overlap of my data set but looking for help how to print the Venn graphic. Can anyone provide assistance? I read through the documentation but didn't find this.
> library('VennDiagram')
# A simple single-set diagram
cardiome <- letters[1:10]
superset <- letters[8:24]
overlap <- calculate.overlap(
x = list(
"Cardiome" = cardiome,
"SuperSet" = superset
)
);

Answer 1

Another simple example that shows how to print a Venn diagram using the VennDiagram package:
library(VennDiagram)
cardiome <- letters[1:10]
superset <- letters[8:24]
overlap <- calculate.overlap(
x <- list("Cardiome"=cardiome, "SuperSet"=superset))
venn.plot <- draw.pairwise.venn(
area1 = length(cardiome),
area2 = length(superset),
cross.area = length(overlap),
category = c("Cardiome", "Superset"),
fill = c("blue", "red"),
lty = "blank",
cex = 2,
cat.cex = 2,
cat.pos = c(180, 180),
cat.dist = 0.05,
cat.just = list(c(0, 1), c(1, 1))
)
grid.draw(venn.plot)
savePlot(filename="venndiag", type="png")
Venn diagrams with item labels inside the sets:
library(RAM)
vectors <- list(Cardiome=cardiome, Superset=superset)
group.venn(vectors=vectors, label=TRUE,
fill = c("blue", "red"),
cat.pos = c(180, 180),
lab.cex=1.1)

Answer 2

The funtion venn.diagram() does it. For instance in your example
venn.diagram(x = list(
"Cardiome" = cardiome,
"SuperSet" = superset
), "plot_venn")
It saves to working directory. Type getwd() to see what it is set to.
See the
?venn.diagram()
for more info.

Answer 3

?venn.diagram suggests this
library('VennDiagram')
venn.plot <- venn.diagram(
x = list(
cardiome = letters[1:10],
superset = letters[8:24]
),
filename = NULL
);
grid.draw(venn.plot);
