  \itemize{
    \item{dayOfYear}{
      a numeric vector = 1:365 with names 'jan01' to 'dec31'.
    }
    \item{dayOfYearShifted}{
      a numeric vector = c(182:365, 1:181) with names 'jul01' to
      'jun30'.
    }
    \item{day.5 }{
      a numeric vector = dayOfYear-0.5 = 0.5, 1.5, ..., 364.5
    }
    \item{daysPerMonth}{
      a numeric vector of the days in each month (ignoring leap years)
      with names = month.abb
    }
    \item{monthEnd}{
      a numeric vector of cumsum(daysPerMonth) with names = month.abb

    \item{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)

    \item{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)

    \item{monthMid}{
      a numeric vector of the middle of the month = (monthBegin.5 +
      monthEnd.5)/2
    }
    \item{monthLetters}{
      A character vector of c("j", "F", "m", "A", "M", "J", "J", "A",
      "S", "O", "N", "D"), with 'month.abb' as the names.
    }
    \item{weeks}{
      a numeric vector of length 53 marking 52 periods of approximately 7
      days each throughout the year = c(0, 365/52, ..., 365)
    }
  }

  Miscellaneous vectors often used in 'fda' scripts.
