read_mnemos: Reads data provided by MNEMOS software (SNIH - Argentina)

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

Reads data provided by MNEMOS software (SNIH - Argentina)

Description

Reads xlsx files generated with MNEMOS software.

Usage

read_mnemos(
  path,
  by = "none",
  out_name = NULL,
  sheet = NULL,
  skip = 3,
  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' ). 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.
skip	optional. Minimum number of rows to skip before reading anything, be it column names or data. Leading empty rows are automatically skipped, so this is a lower bound.
get_sheet	logical indicating whether you want to print available variables (TRUE) in every file sheet or not.

Value

A data frame with the data inside the specified sheet. Gaps between dates are filled with NA_real_ and duplicated rows are eliminated automatically. In case you set get_sheet = TRUE the function will return a list with the variables inside each sheet.

Examples

# list mnemos files
list.files( system.file('extdata', package = 'hydrotoolbox'), pattern = 'mnemos' )

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

# we can see which variables are inside the sheet's file
read_mnemos(path = path, get_sheet = TRUE)

# now we want to read the maximum temperature
tmax_guido <- read_mnemos(path = path, by = 'day',
                          out_name = 'tmax(ºC)', sheet = '11413-016')
