Numeric and character vectors to facilitate working with dates
Description
Numeric and character vectors to simplify functional data computations
and plotting involving dates.
Format
- dayOfYear
- a numeric vector = 1:365 with names 'jan01' to 'dec31'.
- dayOfYearShifted
- a numeric vector = c(182:365, 1:181) with names 'jul01' to
'jun30'.
- day.5
- a numeric vector = dayOfYear-0.5 = 0.5, 1.5, ..., 364.5
- daysPerMonth
- a numeric vector of the days in each month (ignoring leap years)
with names = month.abb
- monthEnd
- a numeric vector of cumsum(daysPerMonth) with names = month.abb
- monthEnd.5
- a numeric vector of the middle of the last day of each month with
names = month.abb = c(Jan=30.5, Feb=58.5, ..., Dec=364.5)
- monthBegin.5
- a numeric vector of the middle of the first day of each month with
names - month.abb = c(Jan=0.5, Feb=31.5, ..., Dec=334.5)
- monthMid
- a numeric vector of the middle of the month = (monthBegin.5 +
monthEnd.5)/2
- monthLetters
- A character vector of c("j", "F", "m", "A", "M", "J", "J", "A",
"S", "O", "N", "D"), with 'month.abb' as the names.
- weeks
- a numeric vector of length 53 marking 52 periods of approximately 7
days each throughout the year = c(0, 365/52, ..., 365)
