An implementation of the constrained quadratic regression algorithm using a flexible window size described in Wood (1996).
Usage
wbt_local_quadratic_regression(
dem,
output,
filter = 3,
wd = NULL,
verbose_mode = NULL,
compress_rasters = NULL,
command_only = FALSE
)
Arguments
- dem
Name of the input DEM raster file.
- output
Name of the output raster file.
- filter
Edge length of the filter kernel.
- wd
Changes the working directory. Default:
NULL
will use the value in WhiteboxTools settings, seewbt_wd()
for details.- verbose_mode
Sets verbose mode. If verbose mode is
FALSE
, tools will not print output messages. Default:NULL
will use the value in WhiteboxTools settings, seewbt_verbose()
for details.- compress_rasters
Sets the flag used by 'WhiteboxTools' to determine whether to use compression for output rasters. Default:
NULL
will use the value in WhiteboxTools settings, seewbt_compress_rasters()
for details.- command_only
Return command that would be executed by
system()
rather than running tool. Default:FALSE
