How to create a Venn Diagram using R?

I created a Venn Diagram using the eulerr package but it doesn't let me customize it and the outlines of the inner circles seem to touch the sample space circle. I looked through the VennDiagram package manual but had no luck. Is there a way to create a Venn Diagram using either ggplot2 or any other R packages.

I am looking to do what this user was trying to do with the data I have. 3 sets that fall into the complete sample space. How to draw a venn diagram subset by a main vector in R

This is what was created using the eulerr package:

This is the data that I have. Circles B, C, and D should be inside circle A which has a total of 141. The 35 in variable a is the space between the 3 venn diagram and the circle (white space).

b = c(50,0,9,2,1,0,0,0)
c = c(50,21,0,2,0,3,0,0)
d = c(50,21,9,2,0,3,20,0)
a = c(50, 21, 9, 2,1,3,20,35)

totes = cbind(b, c, d, a)

I don't know how to go about this and make a presentable diagram that I can customize.

When I used the eulerr package, I manually entered the data in the command.

You may consider my nVennR package. With your data,

>library(nVennR)
> myV <- plotVenn(list(b = c(50,9,2,1),
+                      c = c(50,21,2,3),
+                      d = c(50,21,9,2,3,20),
+                      a = c(50, 21, 9, 2,1,3,20,35)))
> showSVG(myV, opacity = 0.2, borderWidth = 1)

And the result:

cont2

You can also list the elements in each region:

> listVennRegions(myV)
$`0, 0, 0, 1 (a)`
[1] 35

$`0, 0, 1, 1 (d, a)`
[1] 20

$`0, 1, 1, 1 (c, d, a)`
[1] 21  3

$`1, 0, 0, 1 (b, a)`
[1] 1

$`1, 0, 1, 1 (b, d, a)`
[1] 9

$`1, 1, 1, 1 (b, c, d, a)`
[1] 50  2

Please, notice that I removed the zeroes in your list. The package takes those zeroes as elements, which were not present in list a. If you are interested, you can find a vignette and a web interface for the algorithm.
