getDailyMean function

Calculates the daily means of a range of days around each date of a data frame corresponding to a period between year_min and year_max for stations listed in station

getDailyMean(data, year_min = 1961, year_max = 1990,
  station = c("T0001", "T0010"), origin = "1961-1-1", lag = 5)

Arguments

• data: a data frame containing daily data.
• year_min: start year
• year_max: end year
• station: character vector of the IDs of the station where the data are requested
• origin: origin date of time-series
• lag: lag (number of days) on which daily mean is calculated. The mean is calculated considereing lag days before and after each day.

Returns

a matrix containing the requested daily mean data where each day corresponds to a row and each station corresponds to a column

Note

The input data frame data must have the following fields: year,month,day,variables_ID1,variables_ID2,...

where the fields ,variables_ID1,variables_ID2,... contain the daily variables referred to the respective stations and the field names are replaced with the respective station ID.
