bin {partitions} | R Documentation |
Utilities to convert things to binary
tobin(n, len, check=TRUE) todec(bin) comptobin(comp, check=TRUE) bintocomp(bin, use.C=TRUE, check=TRUE)
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 0 s and 1 s |
comp |
A composition |
check |
Boolean, with default TRUE meaning to perform
various checks |
use.C |
Boolean, with default TRUE meaning to use
C |
These functions are not really intended for the end user; they are
used in nextcomposition()
.
tobin()
converts integer n
to a binary
string of length len
todec()
converts a binary string to decimal,
so todec(tobin(n,i))==n
, provided i
is big enough
comptobin()
converts a composition to binary
bintocomp()
converts a binary string to a
composition
