whiteboxing {ursa}

Wrapper to WhiteboxTools

Description

Wrapper to tools from "whitebox" package to manipulate with ursaRaster objects

Usage

whiteboxing(tool_name, ...)

Arguments

tool_name

Either tool name of Whitebox or function name from whitebox.

...

List of parameters.

Details

Wrapper to function wbt_run_tool.

ursaRaster object foo can be passed via parameter input=foo instead of GeoTIFF file name.

Value

If argument output is missed or output=FALSE, then object of class ursaRaster. Otherwise, output GeoTIFF file name.

Note

Internally, for piping support, first character argument without *.tif suffix is interpreted as tool_name. First unnamed character argument with *.tif suffix or ursaRaster object is interpreted as input.
