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.

- Current version:
**2.4.0**

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.

The R function naming style differs from the tool names in WhiteboxTools, but the core words are the same.

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

```

Several fields in this table such as `flags`

and
`parameter_type`

are “flattened” relative to the nested
`wbt_tool_parameters()`

output.

The nested `parameter_type`

from the JSON result is
replaced with two variables in the data set:
`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.

```
str(wbttoolparameters, max.level = 1)
#> 'data.frame': 2198 obs. of 13 variables:
#> $ tool_name : chr "AbsoluteValue" "AbsoluteValue" "AccumulationCurvature" "AccumulationCurvature" ...
#> $ function_name : chr "wbt_absolute_value" "wbt_absolute_value" "wbt_accumulation_curvature" "wbt_accumulation_curvature" ...
#> $ toolbox_name : chr "Math and Stats Tools" "Math and Stats Tools" "Geomorphometric Analysis" "Geomorphometric Analysis" ...
#> $ name : chr "Input File" "Output File" "Input Raster DEM" "Output Raster Image" ...
#> $ flags : chr "-i,--input" "-o,--output" "-i,--dem" "-o,--output" ...
#> $ description : chr "Input raster file." "Output raster file." "Name of the input raster DEM file." "Name of the output raster image file." ...

#> $ is_output : logi FALSE TRUE FALSE TRUE FALSE FALSE ...
#> $ argument_name : chr "input" "output" "dem" "output" ...
#> - attr(*, "version")= chr "2.4.0"
```

You will find that both `tool_name`

and
`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()`

.

```
