In hydrotoolbox: Hydrological Tools for Handling Hydro-Meteorological Data Records

Reads data from Departamento General de Irrigación - Hydrological Division (DGI - Mendoza - Argentina)

Description

Reads excel files provided by the DGI (Hydrological Division).

Usage

read_dgi(path, by = "day", out_name = NULL, sheet = NULL, get_sheet = FALSE)

Arguments

path	path to the xlsx file.
by	string with the time step of the series (e.g.: 'month', 'day', '6 hour', '3 hour', '1 hour', '15 min' ). By default this argument is set to 'day'. If you set it as 'none', the function will ignore automatic gap filling.
out_name	optional. String vector with user defined variable(s) column(s) name(s).
sheet	optional. Sheet to read. Either a string (the name of a sheet), or an integer (the position of the sheet). If neither argument specifies the sheet, defaults to the first sheet.
get_sheet	logical indicating whether you want to print available sheet names (TRUE) in the file or not.

Value

A data frame with the data inside the xlsx file. Gaps between dates are filled with NA_real_ and duplicated rows are eliminated automatically.

Examples

# set path to file
path_file <- system.file('extdata', 'dgi_toscas.xlsx',
             package = 'hydrotoolbox')

# because dgi files has multiple sheets we take a look
# on them
read_dgi(path = path_file, get_sheet = TRUE)

# read swe with default column names
head( read_dgi(path = path_file, sheet = 'swe') )

# assign name
head( read_dgi(path = path_file, sheet = 'swe', out_name = 'swe(mm)') )

# now read relative humidity
head( read_dgi(path = path_file, sheet = 'hr', out_name = 'rh(%)') )
