Generate a new land use change scenario in SWAT+

LUCscen(
  scen.name,
  textInOut.path,
  hru.shape,
  lc,
  lookup.table,
  change.yr,
  skip.copy = FALSE,
  jday = 1,
  fact.diss = NULL,
  scen.path = NULL,
  verbose = TRUE,
  exclude.uses = NULL
)

`scen.name`	Object type 'character' with the name of the new scenario to be created.
`textInOut.path`	Path to the default 'TxtInOut' folder. The new scenario will be created from this file.
`hru.shape`	Spatial object of type 'SpatVector' that contains the HRUs that were created in the 'QSWAT+' project.
`lc`	Raster object of type 'SpatRaster' that contains the land cover for the years to be analysed.
`lookup.table`	A three column 'data.frame' object. The first column stores the land use values from the 'lc' object. The second column stores the SWAT_CODE as in the lookup table that is given to 'SWAT+'. Finally, the third column represents the land use (lum) identifiers from ‘SWAT+' as stored in the ’landuse.lum' file.
`change.yr`	Object type 'character' containing the year(s) when the land use changes take place (in chronological order).
`skip.copy`	Logical object. Set tu true only if the files from the default 'TxtInOut' folder have been already copied to the directory of the new scenario.
`jday`	Numerical value that indicates the julian day that the land use change(s) will take place (default jday = 1).
`fact.diss`	Factor of disaggregation of the land cover maps. Sometimes, when the HRUs are very small, this function can return NAs. Therefore, the LU maps are disaggregated using the nearest neighbour. A value of 1 means no disaggregation. See terra::disaggregate for more details.
`scen.path`	Path to the directory where the new scenatio will be created. If not given, the new scenario will be created in the same folder of the default scenario.
`verbose`	Object type 'logical'. Should the progress messages be printed?
`exclude.uses`	Exclude land use classes from the scenario. Currently, the change of urban and water classes cause errors in 'SWAT+'; and therefore, should be avoided.
