digitsBase<br />
Digit/Bit Representation of Integers in any Base<br />
Description<br />
Integer number representations in other Bases.<br />
Formally, for every element N =x[i], compute the (vector of) “digits” A of the base b representation<br />
of the number N, N = ∑ M<br />
k=0 A M−kb k .<br />
Revert such a representation to integers.<br />
Usage<br />
digitsBase(x, base = 2, ndigits = 1 + floor(log(max(x), base)))<br />
## S3 method for class 'basedInt':<br />
as.integer(x, ...)<br />
## S3 method for class 'basedInt':<br />
print(x, ...)<br />
as.intBase(x, base = 2)
