R: Record app information in a convenient object

app_dir {rappdirs} | R Documentation

## Record app information in a convenient object

### Description

Has methods:

- `$cache()`

- `$log()`

- `$data()`

- `$config()`

- `$site_data()`

- `$site_config()`

### Usage

    app_dir(
      appname = NULL,
      appauthor = appname,
      version = NULL,
      expand = TRUE,
      os = NULL
    )

### Arguments

`appname` | is the name of application. If NULL, just the system directory is returned.
`appauthor` | (only required and used on Windows) is the name of the appauthor or distributing body for this application. Typically it is the owning company name. This falls back to appname.
`version` | is an optional version path element to append to the path. You might want to use this if you want multiple versions of your app to be able to run independently. If used, this would typically be `"<major>.<minor>"`. Only applied when appname is not NULL.
`expand` | If TRUE (the default) will expand the `R_LIBS` specifiers with their equivalents. See `R_LIBS()` for list of all possibly specifiers.
`os` | Operating system whose conventions are used to construct the requested directory. Possible values are "win", "mac", "unix". If `NULL` (the default) then the current OS will be used.

### Examples

    ggplot2_app <- app_dir("ggplot2", "hadley")
    ggplot2_app$cache()
    ggplot2_app$log()
    ggplot2_app$data()
    ggplot2_app$config()
    ggplot2_app$site_config()
    ggplot2_app$site_data()
