Hi,
I am looking for functions that would allow me to access raw binary data of
R vectors. One way would be to use:
x = (1:10)*pi
writeBin(x, "temp.bin")
r = readBin("temp.bin", "raw", n=length(x)*8)
Other to write my own C code. Is there any other simpler way?
I this message is a rewording of my yesterday message "Looking for function
for Double to raw to double conversions", to which I got no replies. I need
this functionality to implement Base64 encoding for reading/writing XML
files.

Yes, XML package does not seem to support Base64 encoding so I wrote my own encoder/decoder working with "raw" vectors. The only problem is casting R's vectors of doubles into vectors of type "raw".
