Hello,
Thank you for such a useful package. I am however having difficulty running some of these functions in sequence, producing the following error:

Error in RegParallel(data = rlddata, formula = "[*] ~ Lineage1", FUN = function(formula, :
An unknown error has occurred. Please report on Bioconductor support site: https://support.bioconductor.org/t/Latest/
In addition: Warning messages:

2: In unique(res$Variable) == variables :

Is there a solution to this?
