| as.binary {rdiversity} | R Documentation |
as binary digit.
Description
Converts an integer (Base10) to a binary (Base2) number. It also converts a logical vector to a binary (Base2) number (see examples).
Usage
as.binary(x, signed=FALSE, littleEndian=FALSE, size=2, n=0, logic=FALSE)
Arguments
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. |
Details
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.
Value
a vector of class binary.
