whitebox Tool MetadataThis vignette provides an introduction to the data sets included in
the whitebox package. These data sets contain names,
arguments and other metadata for tools available in WhiteboxTools.
Internal data sets and functions defined in the R package correspond to tool names available in the most recent version of WhiteboxTools. Data sets are not dynamically generated from your WhiteboxTools installation. Relatively recent versions of WhiteboxTools should be supported backward-compatibly, though any newer functionality will not be usable.
The first data set describes tool names in WhiteboxTools and the corresponding exported function in the R package, along with the WhiteboxTools Toolbox name and a brief description.

R function names are derived from the WhiteboxTools name as follows:
PascalCase tool names change to
snake_case
All R function names get the prefix wbt_
For example, StreamSlopeContinuous in WhiteboxTools
becomes wbt_stream_slope_continuous() in R.
The second data set provides details about the available function arguments by tool name.
The wbttoolparameters data set is a data.frame
with 2198 parameters and 13 variables:
"tool_name" - WhiteboxTools tool name
"function_name" - R function name
"toolbox_name" - WhiteboxTools toolbox name
"name" - WhiteboxTools tool parameter name
"flags" - flags used to specify parameter on command
line; comma-separated
"description" - parameter description
"default_value" - parameter default value, if
any
"optional" - parameter “optional” flag; note that
some combination of optional parameters may be required for certain
conditions
"parameter_class" - parameter type
"parameter_detail" - parameter details; character:
data type followed by colon and more specifics, For OptionList possible
values, comma-separated (if defined)
"is_input" - logical. Classification of ‘input’
parameters
"is_output" - logical. Classification of ‘output’
parameters
"argument_name" - labels for selected subset of
"flags" used as R function argument names
for wbt_ functions

parameter_class and parameter_details
This parameter data.frame is useful to construct your own
functions with wbt_run_tool() or for inspecting the types
of tools that can be run on particular data types.

function_name are present, so you can look up by whatever
is convenient.
The variable argument_name is processed to be the subset
of flags that corresponds to arguments to R functions,
which are denoted with function_name.
To find the tools that have an “ExistingFile” argument with file type
“Raster” we can use subset().
