Hi, thanks for creating Sccomp! It's a great tool.

I'm trying to use a continuous-valued variable as a main effect in sccomp, and when I try it I get an error. Is sccomp able to be used with continuous variables as the main effect?

Here's a reprex:

library(sccomp)
data(counts_obj)
#add sample continuous variable as main effect
counts_obj$contin_var = runif(nrow(counts_obj))
sccomp_result = 
  counts_obj |>
  sccomp_estimate( 
    formula_composition = ~ contin_var, 
    .sample = sample,
    .cell_group = cell_group,
    .count = count, 
    bimodal_mean_variability_association = TRUE,
    cores = 1, verbose = FALSE
  ) |> 
  sccomp_remove_outliers(cores = 1, verbose = FALSE) |> # Optional
  sccomp_test()

The actual error I get is:
Warning: non-unique values when setting 'row.names': ‘10x_6K’, ‘10x_8K’, ‘GSE115189’, ‘SCP345_580’, ‘SCP345_860’, ‘SCP424_pbmc1’, ‘SCP424_pbmc2’, ‘SCP591’, ‘SI-GA-E5’, ‘SI-GA-E7’, ‘SI-GA-E8’, ‘SI-GA-G6’, ‘SI-GA-G7’, ‘SI-GA-G8’, ‘SI-GA-G9’, ‘SI-GA-H1’, ‘SI-GA-H3’, ‘SI-GA-H4’, ‘SRR11038995’, ‘SRR7244582’
