Thanks! So it looks like I can say "R writeBin/readBin does not support
half-precision floats" even though the error message "size 2 is unknown on
this machine" seems to contradict that (for some machine). I tried to
figure out from the source code (src/main/connections.c) how it decides
what

Sorry about the dead lead on the package... it is hexView. It does not support
FP16 directly though... You would have to find another way to make that
conversion. Some people have posted code that may be usable with Rcpp [1]. I
believe your architecture may support hardware conversion of FP32 t

Following the posting guide and hence reading the help page first helps:
"Possible sizes are 1, 2, 4 and possibly 8 for integer or logical
vectors, and 4, 8 and possibly 12/16 for numeric vectors."

Thanks for the pedantic insult, but no thanks. I'd rather just hear if
anyone reading this is able to make something like this work on any
architecture:
vec <- 1:10/10
con <- file( "test.bin16", "wb" )
writeBin( vec , con, size=2 )
close(con)
If they can do it, they can tell me about it. Tha
Your message is missing either a reproducible example or an indication of your
R environment (such as the output of sessionInfo()).
Yes, the machine architecture can prevent certain types of operations. This is
however a poor venue for discussing such issues.
I suggest that you investigate the
