## Generate Chron or Dates Sequences

### Description

Generate a regular sequence of dates.

### Usage

    ## S3 method for class 'dates'
    seq(from, to, by = "days", length., ...)

### Arguments

`from` | starting date; it can be a chron or dates object, a character string, e.g., `"05/23/91"`, or a Julian date.
`to` | ending date, like `from`.
`by` | either a numeric value or one of the valid strings `"days"`, `"weeks"`, `"months"`, or `"years"`.
`length.` | optional number of elements in the sequence.
`...` | further arguments to be passed to or from methods.

### Value

a sequence with values (`from`, `from + by`, `from + 2*by`, ..., `to`) of class `class(from)` and origin `origin(from)`. Note that `from` must be less than or equal to the argument `to`.

### Examples

    seq.dates("01/01/92", "12/31/92", by = "months")
    # [1] 01/01/92 02/01/92 03/01/92 04/01/92 05/01/92 06/01/92
    # [7] 07/01/92 08/01/92 09/01/92 10/01/92 11/01/92 12/01/92

    end.of.the.month <- seq.dates("02/29/92", by = "month", length = 15)
    end.of.the.month
    #  [1] 02/29/92 03/31/92 04/30/92 05/31/92 06/30/92 07/31/92
    #  [7] 08/31/92 09/30/92 10/31/92 11/30/92 12/31/92 01/31/93
