Hi everyone, not an expert here. maybe someone can help: How do I make the Deficit flow start below/aligned with Budgetary revenues. All my flows are starting at the beginning. 
I tried custom_positions <- tibble::tribble( ~name, ~x, ~y, "Deficit", 0.6, 0.5), but it's not working. Here is my code.
Packages
pkgs <- c("dplyr", "tidyr", "tibble", "networkD3", "htmlwidgets")
to_install <- setdiff(pkgs, rownames(installed.packages()))
if (length(to_install)) install.packages(to_install)
lapply(pkgs, library, character.only = TRUE)
Data
flows <- tibble::tribble(
~source, ~value, ~target, ~hex,

The issue is that i have to realign all the blue with the blue and all the grey with grey. I have the perfect sankey with sankeymatic but I wanted a shinyapp for it .
