My question is about the function 'chordDiagram' of the 'circlize' package in R. I wonder if there is a possibility to color the links between the different groups with a smooth color gradient of the two groups. We set the colors of the groups with the 'grid.col' argument and the colors of the links with the 'col' argument.
Is there a way, for each link to get a smooth gradient between the two colors set in grid.col for the 2 groups? I've seen that this is doable in other programs than R but I wonder if anyone has already faced the same issue. Here is an example of what I am trying to obtain. [Example of smooth gradients between groups]
Thank you very much in advance for your help.
