I think it might be the cause of "attr(*, "names")", but trying to fix it hasn't solved it yet. I wonder if anyone has similar problems. I hope you can get an answer, thanks!

I solved this by adding more than one celltype.
select.ct = c('CD28', 'CD138)

This is because R automatically coverts a matrix into a vector when selecting only one column. little annoying!
