Returns the tool text outputs.
Name of the input DEM raster file; must be depressionless.
Name of the output raster file.
Output type; one of 'cells', 'specific contributing area' (default), and 'catchment area'.
Optional upper-bound exponent parameter; default is 10.0.
Optional upper-bound slope parameter, in degrees (0-90); default is 45.0.
Optional convergence threshold parameter, in grid cells; default is infinity.
Log-transform the output values?.
Optional flag to request clipping the display max by 1 percent.
Changes the working directory. Default: NULL
will use the value in WhiteboxTools settings, see wbt_wd()
for details.
Sets verbose mode. If verbose mode is FALSE
, tools will not print output messages. Default: NULL
will use the value in WhiteboxTools settings, see wbt_verbose()
for details.
Sets the flag used by 'WhiteboxTools' to determine whether to use compression for output rasters. Default: NULL
will use the value in WhiteboxTools settings, see wbt_compress_rasters()
for details.
Return command that would be executed by system()
rather than running tool. Default: FALSE
