c(NA, 0+1i) not the same as c(as.complex(NA), 0+1i)?
Hmm, it is not actually at odds with help(c), it is just that the autocoercion works different that it used to, so that
as.complex(NA) == as.complex(NA_real) == NA_real_+0i)
which now differs from
NA_complex
although both print as NA.
I haven't been quite alert when this change was discussed, but it does look a bit unfortunate that usage patterns like c(NA, 0+1i) do...

c(NA, 0+1i) not the same as c(as.complex(NA), 0+1i)?
This is another follow-up to the thread from September "Recent changes to
as.complex(NA_real_)".
A test in data.table was broken by the changes for NA coercion to complex;
the breakage essentially comes from
c(NA, 0+1i)
# vs
c(as.complex(NA), 0+1i)
The former is the output we tested against; the latter is essentially (via
coerceVector() in C) what's generated by our
