wbt_local_quadratic_regression {whitebox}

Local quadratic regression

Description

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, see wbt_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, see wbt_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, see wbt_compress_rasters() for details.

command_only

Return command that would be executed by system() rather than running tool. Default: FALSE.

Value

Returns the tool text outputs.
