For input connections, I wrote code to populate the old text connection buffer from a raw vector, and provided a new raw_read() method. For output connections, I wrote a raw_write() to append to a raw vector. On input, the mode (text or binary) is determined by the data type of the input object; on output, I use the requested output mode (i.e. "w" / "wb"). For example: > con <- loopConnection("r", "wb") > a <- c(10,10...
