Thank you both, You are absolutely correct that example should be minimal, so here it is.
l = list(a=new.env(), b=new.env()) unique(l) Just for completeness, env_list during check that raises error env_list <- list(baseenv(), as.environment("package:graphics"), as.environment("package:stats"), as.environment("package:utils"), as.environment("package:methods") ) unique(env_list) Best regards, Jan On Mon, Jun 29, 2020 at 5:42 PM Martin Maechler <maech...@stat.math.ethz.ch> wrote: > > >>>>> Kurt Hornik > >>>>> on Mon, 29 Jun 2020 16:13:03 +0200 writes: > > >>>>> Jan Gorecki writes: > >> So the unique.default is from the R tools package during > >> checks.
