Hi,

Did you try cols argument instead of cols.use. I guess this might depend on the Seurat version that you have.

So, I tried the following and it works:

library("Seurat")
packageVersion("Seurat") # ‘3.1.5’
data("pbmc_smal") # import example data
RidgePlot(object = pbmc_small, features = 'PC_1', cols = c("red", "blue", "green")) # plot ridge plot

Result:

c("red", "blue", "green") follows the order at c("severe", "mild", "healthy_control").

I hope this answers your question,

António

I like the last part that you've added to our template. Mind if I steal it and make it part of the template?
