CreateOriginPeriods

Description

This will create a set of origin period values

Usage

  CreateOriginPeriods(OriginStart, OriginEnd = NULL,
    OriginLength = years(1), StartDay = 1, StartMonth = 1,
    Verbose = FALSE)

Arguments

Details

If the triangle dataframe does not have lubridate intervals, they must be created. Origin periods may be established one of three ways: 1. The origin periods are passed in as POSIX dates. This is a simple matter of forming the interval using lubridate. 2. The origin periods are passed in with a start date, but no end date. We need to have a common period to establish the end date. 3. The origin periods are passed in as parts of a date. This will typically happen if we know the year, but not the month or day. In this case , the user may pass in month and day values

Value

A vector of intervals

Examples

# Case 1
library(lubridate)
OriginStart = c(mdy("1/1/2000"), mdy("1/1/2000"), mdy("1/1/2001"))
OriginEnd = c(mdy("12/31/2000"), mdy("12/31/2000"), mdy("12/31/2001"))

OriginPeriods = CreateOriginPeriods(OriginStart, OriginEnd)
OriginPeriods

# Case 2
OriginStart = c(mdy("1/1/2000"), mdy("1/1/2000"), mdy("1/1/2001"))
OriginPeriods = CreateOriginPeriods(OriginStart, OriginLength = months(12))
OriginPeriods

# Case 3
OriginStartYear = c(2000, 2000, 2001)
OriginPeriods = CreateOriginPeriods(OriginStartYear, OriginLength = years(1)
                                     , StartDay = 1, StartMonth = 1)
