nextn {stats} | R Documentation |

## Highly Composite Numbers

### Description

`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.

### Usage

nextn(n, factors = c(2,3,5))

### Arguments

`n` |
an integer. |

`factors` |
a vector of positive integer factors. |

### See Also

`convolve`

, `fft`

.

### Examples

table(sapply(599:630, nextn))
