setting label size different to text size?

[Pakillo]

Hi @nrennie

I need to set different sizes for text in nodes and labels, respectively. As far as I can see, it could be as easy as adding a new parameter label_size here (currently label size is fixed the same as text_size).

Please let me know if you would like a pull request with that minor change, or if there are better ways to achieve that. I've been looking for a way to change label size afterwards, but it doesn't look straightforward (https://stackoverflow.com/questions/42006040/how-to-change-font-size-of-geom-text-post-ex)

Thanks!

Actually it's not that hard to change label size afterwards (reprex below), so maybe there's no need for a label_size argument. But let me know if you'd like a pull request anyway

Cheers!

library(ggflowchart)

data <- tibble::tibble(
  from = c("A", "A", "A", "B", "C", "F"),
  to = c("B", "C", "D", "E", "F", "G"),
  label = c("Yes", "No", NA, "Yes", NA, NA)
)

gg <- ggflowchart(data)
gg$layers[[4]]$aes_params$size <- 8
gg

Hi @Pakillo, this sounds like a reasonable adjustment. If you want to submit a PR, that would be great! Otherwise, you can leave the issue open and I can add the argument in soon(ish).

I would suggest calling the argument arrow_label_size or arrow_text_size to distinguish it from text_size more clearly and to match with arrow_label_fill, and set the default value equal to text_size to ensure backwards compatibility.
