Reads a SWAT output file of the *.rch (reach), *.sub, and *.hru formats. Currently, only the formats as documented in the SWAT 2012 handbook are supported.

1 2	read.swat(filename, filetype = substr(filename, nchar(filename) - 2, nchar(filename)), version = 2016, variables = NULL)

`filename`	character: name of the SWAT file
`filetype`	character: official file extension of SWAT output file ('rch', 'sub', 'hru')
`version`	integer/numeric: SWAT output version, only 2012 and 2016 (equal) are implemented
`variables`	character array of variable names (==columns) to read in from the file; if == NULL [default], all variables are read

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).

The data.frame out$data which contains the data from the file 'filename'; column names of as.data.frame should be equal to column names in the reach file; only variables/columns listed in 'variables' are returned;
