bs_write_byte: Read/Write unaligned bytes with a bitstream

Description

Read/Write unaligned bytes with a bitstream

Usage

bs_write_byte(bs, x)
bs_read_byte(bs, n)

Value

Reading returns a logical vector of bit values. When writing, the bs

bitstream connection is returned invisibly

Arguments

bs

Bistream connection object created with bs_open()

x

vector of bytes to write. Integer vectors will be truncated to 8 bits before output. Numeric vectors will be rounded to integers and then truncated to 8 bits.

n

number of bytes to read

Examples

bs  <- bs_open(raw(), 'w')
bs_write_bit(bs, c(TRUE, FALSE))
bs_write_byte(bs, c(1, 2, 3))
bs_align(bs)
raw_vec <- bs_close(bs)

bs  <- bs_open(raw_vec, 'r')
bs_read_bit(bs, 2)
bs_read_byte(bs, 3)
bs_close(bs)
