| nextn {stats} | R Documentation |
nextn returns the smallest integer,
greater than or equal to n, which can be obtained
as a product of powers of the values contained in factors.
nextn is intended to be used to find a suitable length
to zero-pad the argument of fft to
so that the transform is computed quickly.
The default value for factors ensures this.
nextn(n, factors = c(2,3,5))
