getVolumes: Get a list of available volumes

In moj-analytical-services/s3browser: A R Studio Addin that allows you to browse the files you have access to in S3

Description

This function is intended as an input to the roots parameter in fileGetter and shinyFileChoose. It returns a function that returns a named vector of available volumes on the system. This construction makes it dynamic so that a shinyFiles instance reflects new volumes as they get added (e.g. usb drives). The function takes a single argument giving names of volumes the developer wants removed from the return value.

Usage

getVolumes(exclude)

Arguments

exclude

A vector of volume names to be excluded from the return value

Details

The function is OS specific and looks for volumes/drives in different places depending on the system on which shiny is running.

Windows

Mac OSX

Looks in /Volumes/ and lists the directories therein

Linux

Returns the system root

If the function does not recognize the system under which it is running it will throw an error

Value

A function returning a named vector of available volumes
