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))
n |
