Dear R-devel, Is there anything that we can do to make output of those call more consistent? So the first one will return `c(1L, 2L)` rather than `1:2`. Note that it is not related to compact integer sequence introduced by altrep, it is reproducible on R 3.1.0 as well. substitute(v+x, list(x=c(1L,2L))) #v + 1:2 substitute(v+x, list(x=c(0L,2L))) #v + c(0L, 2L) Thank you, Jan Gorecki

That's purely the deparser (the returned value from substitute doesn't contain a call to ":"), but it's not optional. So the output is consistent, it's the printing that is inconsistent. Duncan Murdoch
