In neumannd/riverdata: Reads river runoff and load data in different formats into R

Description

This function reads data from an already opened SWAT reach (*.rch) file of the SWAT 2012 format.

Usage

read.swat.data.rch.2012(fileHandle, nrow.data, header = TRUE, nreach = 1,
  ireach = 1)

Arguments

fileHandle	open connection to a file; the pointer in the file has to point to the header row if 'header=TRUE'; if 'header=FALSE' it has to point to the first data row
nrow.data	number of data rows to read
header	logical: consider the first row as header row (or not) [default = TRUE]
nreach	integer: number of reaches in the file
ireach	integer: index of the reach's data to extract

Value

list containing a data.frame (out$data), a character array (out$units), and two character variables (out$format and out$tstep). The first contains the actual data formatted as a data.frame. The second contains the units to the corresponding columns of the data.frame. The third contains the source/format of data (here: 'swat'; can also be 'mom'). The fourth contains information on the time step of the data (resp.: on which time interval they are averaged).
