## 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)

### Details

Miscellaneous vectors often used in 'fda' scripts.
