Coersion.from.mondate-methods: Coersion Methods for Mondates
In mondate: Keep Track of Dates in Terms of Months

Description Usage Arguments Methods Examples

Methods to coerce a mondate to other R objects. Currently that includes numbers, characters, and three classes of dates.

 ## S3 method for class 'mondate'
as.character(x, format, ...)
 ## S3 method for class 'mondate'
as.Date(x, ...)
 ## S3 method for class 'mondate'
as.POSIXct(x, ...)
 ## S3 method for class 'mondate'
as.POSIXlt(x, ...)
 ## S4 method for signature 'mondate'
as.numeric(x, convert = FALSE, stripdim = FALSE,  
               timeunits = c("months", "years", "days"), 
               ...)

`x`	a mondate
`format`	the format to give the Date representation of x
`...`	arguments passed to and from other methods
`convert`	See Methods
`stripdim`	See Methods
`timeunits`	See Methods

as.character(x = "mondate", format, ...)

Coerce mondate to class character. Uses the format function.

format: If missing the value is drawn from the displayFormat property of x.
...: arguments passed to other methods (e.g., format).

as.numeric(x = "mondate",

convert=FALSE, stripdim=FALSE, timeunits=c("months", "years", "days"), ...) Coerce mondate to class numeric.

convert:: FALSE (the default) is equivalent to getDataPart. If TRUE the result will be converted to the number of years since the beginning of the millennium if timeunits="years"; to the number of days since the beginning of the millennium if timeunits="days". Also in the case that convert=TRUE the numeric returned will have "timeunits" as an attribute.
stripdim:: FALSE (the default) retains the array attributes dim and dimnames. If TRUE the dimension attributes are stripped, which is the default behavior of base::as.numeric.
timeunits: If missing the value is drawn from the property of the mondate.

as.Date(x = "mondate")

Coerce mondate to class Date

as.POSIXlt(x = "mondate")

Coerce mondate to class POSIXlt

as.POSIXct(x = "mondate")

Coerce mondate to class POSIXct

(b<-mondate(1))              # end of first month of current millennium
as.numeric(b)                # 1
as.character(b)              # December 31, 2000 in date format of locale
as.character(b, format="%b-%Y")  # "Dec-2000"
as.numeric(b, convert=TRUE, timeunits="years") # converts to 1/12 "years"
(b<-mondate(1, timeunits="days")) # end of first day of millennium
as.numeric(b)                # 1/31
as.numeric(b, convert=TRUE)  # 1 (with a "days" attribute)
as.Date(b)                   # displays as "2000-01-31"
as.POSIXct(b)                # displays as "2000-01-31 UTC"
weekdays(as.POSIXct(b))      # January 31, 2000 was a "Saturday" (in English)
as.POSIXlt(b)$hour           # zero, as are ...$min and ...$sec
