R: Sequence Generation of 'ff' vectors.

ffseq {ffbase} | R Documentation

## Sequence Generation of `ff` vectors.

### Description

Similar as `seq` in the base package, generating an `ff` vector.

### Usage

    ffseq(
      from = 1,
      to = 1,
      by = ((to - from)/(length.out - 1)),
      length.out = NULL,
      along.with = NULL,
      ...
    )

### Arguments

`from` | the starting value of the sequence
`to` | the end (maximal) value of the sequence
`by` | number, increment of the sequence
`length.out` | desired length of the sequence. Only non-negative numbers larger than 0 are allowed.
`along.with` | take the length from the length of this argument
`...` | arguments passed to or from methods

### Value

An ff vector with the generated sequence, similar as what `seq` generates but as an ff vector.
Mark: in case this would generate a sequence of length 0, will return integer().

### See Also

### Examples

    ## ffseq_len
    ffseq_len(1000)
    ffseq_len(1000000)

    ## ffseq
    ffseq(from = 1, to = 4, by = 1)
    ffseq(from = 1, to = 4, by = 0.5)
    ffseq(from = 4, to = 1, by = -0.5)
    ffseq(from = -100, to = 100, by = 0.3)
    ffseq(from = 2, to = -100, length.out = 4)
    ffseq(from = 2, to = -100, length.out = 4)
    ffseq(from = 2, along.with=1000)
    ffseq(to = 2, along.with=1000)
    ffseq(along.with=1000)
    ffseq(length.out=1000000)
