Color adjustment

[kotliary]

Nice package.
How can I adjust the colors of circles/elipses and borders with either ggvenn or geom_venn?
Also any way to change transparency, border thickness, etc. Thanks.

Thanks for interest and suggestion. So far It does not allow setting the attributes. But I'd like to improve it to support that.

I have added some parameters (such as fill_color and fill_alpha) to both ggvenn() and geom_venn() to support this feature.

@kotliary Could you please try to reinstall the latest version (v0.1.0) package code and try again? Thanks!

[yanlinlin82]

Solved in v0.1.0.

Sorry for not responding in time. The new features work great. Love the package.

Thank you for the great encouragement! Suggestions are welcome!

Is there a way to map colors by specifying the names of the sets, like c("Set1" = "black", "Set2" = "green")?

hi, @nh-codem

Thank you for the suggestion.

Here are some examples demonstrating the current behavior:

a = list(`Set 1` = 1:5, `Set 2` = 4:7)

ggvenn(a, fill_color = c(`B` = "green", `A` = "black"))
# ggvenn(a, fill_color = c(`Set 2` = "green", `Set 1` = "black")) # NOTICE: this does not work

Currently, the color names must be hard-coded as 'A', 'B', 'C', and 'D' corresponding to the four sets in sequential order. While this approach is not very intuitive, it serves as a temporary workaround. We recognize this limitation and will consider improving it in future updates to allow for more flexible and user-friendly color mapping.
