R: Interactively offers the user to set up the default root path

setupCacheRootPath {R.cache} | R Documentation

## Interactively offers the user to set up the default root path

### Description

Interactively offers the user to set up the default root path.

### Usage

    ## Default S3 method:
    setupCacheRootPath(defaultPath="~/.Rcache", ...)

### Arguments

`defaultPath` | Default root path to set.
`...` | Not used.

### Details

If the cache root path is already set, it is used and nothing is done. If the "default" root path (`defaultPath`) exists, it is used, otherwise, if running interactively, the user is asked to approve the usage (and creation) of the default root path. In all other cases, the cache root path is set to a session-specific temporary directory.

### Value

Returns (invisibly) the root path, or `NULL` if running a non-interactive session.
