cloudstoR

The goal of cloudstoR is to simplify accessing data stored on cloudstor via their WebDAV interface. You can use cloudstoR to download or upload files, or check the contents of directories.

Installation

You can install from CRAN (soon…) with:

install.packages("cloudstoR")

Or install the development version from GitHub with:

# install.packages("devtools")
devtools::install_github("pdparker/cloudstoR")

Setup

You will need your cloudstor username and password. The password is not the one you use to log on to cloudstor. Instead you need to use an app password. cloudstoR provides an option to store these credentials using keyring.

Example

library(cloudstoR)
my_data = cloud_get(path = 'mydata1.csv')

Note that calling any of the cloud_* functions without a username or password prompts cloudstoR to store your credentials locally. You can choose not to do this by providing a username and password.

my_data = cloud_get(path = 'mydata1.csv',
                    username = cloudstor_username,
                    password = cloudstor_appPassword)

Getting a list of files

cloud_list(path = 'cloudstoR Demo')
#> [1] "Another Folder/" "mydata2.csv"

Getting a specific file

my_data = cloud_get(path = 'mydata1.csv')
my_data
#>   A B C
#> 1 1 1 3
#> 2 1 2 2
#> 3 1 3 1

Note that cloudstoR will try to open the file using rio and return a data.frame. If you want to use a different package to open the file, or you just want to download the file without opening it, set open_file = FALSE to return a file path instead.

my_path = cloud_get(path = 'mydata1.csv',
                    dest="~/mydata1.csv",
                    open_file = FALSE)
file.exists(my_path)
#> [1] TRUE

Saving a file to Cloudstor

cloud_put(file_name = 'mydata.sav',
          local_file = '~/datatosave.sav',
          path = 'additional/path/to/folder')

Navigating the folder tree

If you don’t know the exact file path you want to follow, you can find it with cloud_browse().

Updating credentials

If you need to delete your credentials (e.g., because you revoke your app password), you can restore them by calling cloud_auth() directly:

cloud_auth(reset_keys=TRUE)

Using an alternative webdav address

The default webdav address is https://cloudstor.aarnet.edu.au/plus/remote.php/webdav/. If your organisation uses a different address, you can set this globally at the top of your script:

# Set the global webdav address
options(cloudstoR.cloud_address = "https:://my.webdav.address")
# Check the current value
getOption("`cloudstoR`.cloud_address")
