R: Generate Dates and Times Components from Input

dates {chron}

R Documentation

Generate Dates and Times Components from Input

Description

Create objects which represent dates or times.

Usage

dates(x, ...)
times(x, ...)

Arguments

`x`	a chron object, a character vector, or a numeric vector specifying time. If character, it must be in a format recognized by `chron()`. If numeric, it specifies Julian dates, i.e., number of days since an origin.
`...`	parameters for `chron()`.

Value

An object of class dates or times, depending of the function called.

These functions return objects inheriting from dates and times, respectively. They call chron() if x does not belong to any of the chronological classes.

Examples

dts <- dates(c("02/27/92", "02/27/92", "01/14/92",
               "02/28/92", "02/01/92"))
dts
# [1] 02/27/92 02/27/92 01/14/92 02/28/92 02/01/92
class(dts)

x <- chron(dates = c("02/27/92", "02/27/92", "01/14/92", "02/28/92"),
           times = c("23:03:20", "22:29:56", "01:03:30", "18:21:03"))
dates(x)
# [1] 02/27/92 02/27/92 01/14/92 02/28/92
