quarter_year_labels: Time period indexing

In mrc-ide/naomi: Naomi Model for Subnational HIV Estimates

Time period indexing

Description

Time periods are indexed by integers for efficiency and precision. Quarters are indexed as the number of quarters since the beginning of 1900: $quarter_id = (year - 1900) * 4 + quarter$.

Usage

quarter_year_labels(quarter_id)

quarter_number(quarter_id)

quarter_labels(quarter_id)

calendar_quarter_labels(calendar_quarter)

calendar_quarter_labels_short(calendar_quarter)

year_labels(quarter_id)

convert_quarter_id(year, quarter)

convert_calendar_quarter(year, quarter)

calendar_quarter_to_quarter_id(calendar_quarter)

quarter_id_to_calendar_quarter(quarter_id)

calendar_quarter_to_year(calendar_quarter)

calendar_quarter_to_quarter(calendar_quarter)

Arguments

quarter_id	vector of integer quarter IDs.
calendar_quarter	Vector of calendar quarters to convert.
year	vector of integer years.
quarter	vector of integer quarters (1,2,3,4).

Details

Quarters are labelled as "Jan-Mar", "Apr-Jun", "Jul-Sep", "Oct-Dec" instead of "Q1", "Q2", "Q3", "Q4" to avoid confusion between calendar quarters and offset fiscal year quarters.

Examples

quarter_ids <- convert_quarter_id(c(2009, 2017), c(3, 1))
quarter_ids
calender_quarters <- convert_calendar_quarter(c(2009, 2017), c(3, 1))
quarter_number(quarter_ids)
quarter_labels(quarter_ids)
year_labels(quarter_ids)
quarter_year_labels(quarter_ids)
calendar_quarter_labels("CY2015Q2")
calendar_quarter_to_year("CY2015Q2")
calendar_quarter_to_quarter("CY2015Q2")
