bin: Sundry binary functionality

binR Documentation

Sundry binary functionality

Description

Utilities to convert things to binary

Usage

tobin(n, len, check=TRUE)
todec(bin)
comptobin(comp, check=TRUE)
bintocomp(bin,  use.C=TRUE, check=TRUE)

Arguments

n

Integer, to be converted to binary by function tobin()

len

Length of the binary vector returned by function tobin()

bin

Binary: a vector of 0s and 1s

comp

A composition

check

Boolean, with default TRUE meaning to perform various checks

use.C

Boolean, with default TRUE meaning to use C

Details

These functions are not really intended for the end user; they are used in nextcomposition().

  • Function tobin() converts integer n to a binary string of length len

  • Function todec() converts a binary string to decimal, so todec(tobin(n,i))==n, provided i is big enough

  • Function comptobin() converts a composition to binary

  • Function bintocomp() converts a binary string to a composition
