QUESTION
I want to interactively show a VennDiagram::venn.diagram()
in Shiny R.
However, the function venn.diagram()
requires a filename
-attribute as it generates an external TIFF-document.
Thus, what function should I use to generate a venn diagram dynamically based on an user input (input$SELECTION
)?
I suppose I should use the functions draw.single.venn

, but I do not know in advanced how many venns I will need.

What did I do wrong, how can I fix it?
Thank you for your help!

to two hex codes instead of three.
Edit:
Because RColorBrewer::brewer.pal has a lower limit on number of colors you can choose directly (n > 2), in case you want only one or two colors, you first need to specify the palette you want to use and then subset the specific hex codes. For example like so:
