as.binary: as binary digit.
In binaryLogic: Binary Logic

Description Usage Arguments Details Value See Also Examples

Converts an integer (Base10) to a binary (Base2) number. It also converts a logical vector to a binary (Base2) number (see examples).

1	as.binary(x, signed=FALSE, littleEndian=FALSE, size=2, n=0, logic=FALSE)

`x`	integer or logical vector.
`signed`	TRUE or FALSE. Unsigned by default. (two's complement)
`littleEndian`	if TRUE. Big Endian if FALSE.
`size`	in Byte. Needed if signed is set. (by default 2 Byte)
`n`	in Bit. Can be set if unsigned is set to TRUE. (by default 0 Bit = auto)
`logic`	If set to TRUE, x is expected as logical vector.

The binary number is represented by a logical vector. The bit order usually follows the same endianess as the byte order. No floating-point support. If logic is set to TRUE an integer vector is intepreted as a logical vector (>0 becomes TRUE and 0 becomes FALSE)

Little Endian (LSB) —> (MSB)
Big Endian (MSB) <— (LSB)

Auto switch to signed if num < 0.

a vector of class binary.
