R: Production of daily means from hourly temperature series
daily_meanR Documentation

Production of daily means from hourly temperature series

Description

The function works on a list of hourly temperature series. The hourly list is the output of the interpolation function Th_int, called iteratively to produce a list where each component represents one interpolated series.

Usage

  daily_mean(hourly_list, series_names = NULL)

Arguments

hourly_list

the list of hourly temperatures

series_names

names of the serie to be averaged (if NULL (default): all series)

Value

A list of daily averaged series

Note

The first element of hourly_list must be a data frame named "Date" and its columns "year", "month", "day" (a fourth column ("hours") is not used in this function)
