Display big numbers with a comma

[IStevant]

Hi,

would it be difficult to add an option to be able to see the big numbers with commas to make them easier to read?

In the following example I added the total number of items to the labels with paste() and prettyNum() to make them easy to read.
I couldn't find a way to apply prettyNum() to the quantities.

It's not currently possible to do this, but it's a good suggestion. A good approach would be to add an argument that allows the user to specify a function that formats the numbers. Then you could use `prettyNum` or `format` or whatever you want.

This is now supported:

library(eulerr)

fit <- euler(
  c(
    A = 12345,
    B = 6789,
    "A&B" = 2345
  ),
  input = "disjoint"
)

plot(
  fit,
  quantities = list(
    type = "counts",
    format = list(
      fun = prettyNum,
      big.mark = ","
    )
  )
)
