c(NA, 0+1i) not the same as c(as.complex(NA), 0+1i)?
...ng "dilemma" that nobody can help us with is that
"almost infinitely" many different complex numbers z fulfill
is.na(z) |--> TRUE
and only one of them is NA_complex_ and that may be unintuitive.
OTOH, we already have for the doubles that there are at least two
different x fulfulling is.na(x), namely NaN and NA
and from C's point of view there are even considerably more
different NaN's .. but now I'm definitely digressing.

USB boot problems on Gigabyte GA-M55Plus-S3G
...e assumption that I have some
flavor of Linux all set up and ready to run on this specific box (i.e.
the one containg the Gigabyte GA-M55Plus-S3G motherboard).
I don't, actually.
But I may have, in future. Would that help in some way?
Also, on the off chance that I might be in a position to fulfull your
request for the above specific info sometime in the near future, could
you please elaborate and let me know if, by "/dev/sda" in the above,
you intentionally were intendeding to obtain information about the
primary (sATA) hard drive in the system, and *not* about any USB-attached
dev...

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

Actually, it does. The program tells it, that I don't care to read, what's
currently there, by specifying the PROT_READ flag only.
