Hello, I would like to draw a Sankey diagram which shows the relation between differentially expressed genes and pathways. In between these datasets are from different tissues. So I can have tissue information in the middle of diagram. Since not all genes of datasets and pathways are participating in the analysis, so we would definitely have nodes which are not 100 percent. However, Sankey diagram only draw complete nodes (100%). Is there any other package in R that I can use it to draw something similar to Sankey diagram but with not 100% ?
