Issue with coloring DPT plot

[SmritiChawla]

Hi

I am trying to add colors to dpt plot ( 6 colors ) but it is not showing those colors. It is taking some other colors. I am trying to use this command

color_data <- c(
  rep("yellow",92),
  rep("Red",102),
  rep("green",66),
  rep("blue",172),
  rep("black",138),
  rep("magenta",188)
)
p <- plot.DPT(dpt, col = as.vector(color_data))

But these colors are not reflected.
I will be grateful if you resolve this issue. Thank your for consideration

Regards
Smriti

works perfectly for me:

by the way, I very much suggest you

1. don’t use named colors as a color palette (no red, green, …) but instead something like colorbrewer.

2. don’t use a color vector like this. instead, use a factor or integer vector like this:

   cluster_labels <- # an integer of length n_cells
   plot(dpt, col = cluster_labels, palette = brewer.pal(length(unique(cluster_labels)), 'Set1'))
   # or this
   palette(brewer.pal(9, 'Set1'))
   plot(dpt, col = cluster_labels)
