In hzambran/SWAT2R: Input/Output functions for the SWAT hydrological model

Description

Function for reading the ‘output.sed’ files of SWAT 2009 and not in SWAT 2005 (regarding sediment loads), and giving as output a data.frame with the columns of the read file.

The ‘output.sed’ file has 1 row representing the header, 4 columns with the text ‘RCH’, ‘GIS’, ‘MON’, ‘AREA’, and 19 additional colums with results regarding sediments loads on reaches.

Usage

read_sed(file="output.sed", rchID=NA, col.names=NULL, tstep,                    
         Date.Ini, Date.Fin, date.fmt="%Y-%m-%d", verbose=TRUE)

Arguments

file	the name of the file which the data are to be read from. If it does not contain an _absolute_ path, the file name is _relative_ to the current working directory, 'getwd()'. Tilde-expansion is performed where supported.
rchID	OPTIONAL. Integer with the number of the reach for which the results will be provided. If this argument is not provided, the results will be given for all the reaches in ‘output.sed’
col.names	OPTIONAL. character with the column name in file that stores the results that the user wants to convert into a zoo object
tstep	Time step used for the simulation that created the ‘output.sed’ file. It must be one of the following values: c("daily", "monthly", "annual"),
Date.Ini	OPTIONAL, only used when rchID is provided AND it is a unique number. character with the starting date for the results that are stored in file, which is used to provide a zoo object as output.
Date.Fin	OPTIONAL, only used when rchID is provided AND it is a unique number. character with the ending date for the results that are stored in file, which is used to provide a zoo object as output.
date.fmt	character, with the format used to define Date.Ini, Date.Fin. See 'format' in 'as.Date'.
