bits_to_raw

raw_to_bits

Convert between logical vector of bits and raw vector

Bit-level reading and writing are necessary when dealing with
many file formats e.g. compressed data and binary files.  Currently, R
connections are manipulated at the byte level.  This package wraps existing
connections and raw vectors so that it is possible to read bits, bit sequences,
unaligned bytes and low-bit representations of integers.

bits_to_raw function

<dl><dt>bits</dt>
<dd>Logical vector of bit values. Length must be a multiple of 8</dd>
<dt>msb_first</dt>
<dd>MSB first? Default: TRUE</dd>
<dt>x</dt>
<dd>Byte values. Integer vectors will be truncated to 8 bits
before output. Numeric vectors will be rounded to integers and then 
truncated to 8 bits. Raw vectors preferred.</dd></dl>
