fBTd: Daily time base

Description

Construction of a daily time base for solar irradiation calculation

Usage

fBTd(Modo = "DiasProm", 
    Ano = as.POSIXlt(Sys.Date())$year + 1900, 
    FechaInicio = paste("01-01-", Ano, sep = ""), 
    FechaFinal = paste("31-12-", Ano, sep = ""), 
    FechaBaseDatos, FormatoFecha)

Arguments

Modo

character, controls the type of time base to be created. With Modo='BaseDatos' the time series is created according to a solar irradiation database, translating the information about measuring dates contained in FechaBaseDatos. W

Ano

which year is to be used for the time base when Modo='DiasProm'. Its default value is the current year.

FechaInicio

first day of the time base for Modo='Serie'. Its default value is the first of January of the current year.

FechaFinal

last day of the time base for Modo='Serie'. Its default value is the last day of December of the current year.

FechaBaseDatos

numeric vector containing the information about measurement events of the daily solar irradiation database when Modo='BaseDatos'

FormatoFecha

character, defines the format of the information in FechaBaseDatos. It shall follow the rules of the strptime function. For example, '%d-%m-%Y'

Value

• This function returns a data.frame with components adequately obtained from the functions as.POSIXlt and strptime.
• IDd
  numeric, a value which identifies each day of the time series. It is useful for daily summaries when several years are included in the database
• Ano
  numeric, year
• DiaAno
  numeric, day of the year
• Mes
  numeric, month
• DiaMes
  numeric, day of the month
