I have some functions that write an external text file for
postprocessing by another program. Some instructions to the other
program need to be indicated by null values (\000 or ^@). The
function currently uses code like:
writeChar(rawToChar(as.raw(0)), con)
where con is a connection to the file. Previous to version 2.8.0
this worked fine. With 2.8.0 it still works, but I get a warning
message about "truncating string with embedded null: '\0'" every
time. This is documented and not a bug, but I still find it annoying.
Well, why don't you just use
writeChar("", con)
that's what you're actually calling anyway since rawToChar(as.raw(0))
is exactly "" as it gets truncated.
Cheers,

One thing I could do is to turn off all warnings before doing this,
but then if there is some other warning generated, then I will miss
the other warning(s).
Is there a better way to write the null to the text file? Or is
there a way to suppress just this warning without suppressing any
other warnings that may occur?
Thanks,
