A lightweight, high-level R interface for the box.com API, standing on the shoulders of httr
.
You can download boxr from CRAN, with
install.packages("boxr")
If you'd like to download the development version from GitHub, use
# install.packages("devtools")
devtools::install_github("brendan-r/boxr")
Aside from file upload/download, boxr provides functions which mirror base R operations for local files.
box_dl(file_id)
andbox_ul(file = 'path/to/file')
download and upload files, respectivelybox_search()
to query files & folders stored on box.combox_read()
read files straight into R (e.g. .csv or .xlsx files asdata.frames
)box_write()
write R objects to remotely hosted filesbox_setwd()
/box_getwd()
get/set a default box folderbox_source()
read and execute remote codebox_load()
/box_save()
for remote R workspacesbox_add_description()
add text descriptions to your files on box.com
Cloud storage services can complement version control systems for code, which aren't well suited to large binary files (e.g. databases, .RData, or heaps of pdfs). box explicitly versions binary files, keeping old ones, and making it easy fall back to an older copy.
boxr provides git style facilities to upload, download, and synchronize the contents of entire local and remote directories. At the time of writing, the box.com API does not support this directly, and so boxr recursively loops through directory structures.
box_push
will update the remote directory with new/changed local filesbox_fetch
will update the local directory with new/changed remote files
These functions all have overwrite
and delete
parameters, which are set to FALSE
by default.
Disclaimer: box.com is no replacement for a VCS/remote-database, and familiar verbs are no guarantee of expected behavior! Do check the function documentation before jumping in.
boxr's functions have been designed to be 'pipable'. Here's a little example:
library(boxr)
library(dplyr)
library(magrittr)
# 'nycflights13.json' is the same as nycflights13::flights, if you want to
# follow along at home
box_auth()
box_search("nycflights13.json") %>% # Find a remote file
box_read() %>% # Download it as a data.frame
group_by(origin, dest, month) %>% # Do some, er, cutting edge
summarise(mu = mean(arr_delay), n = n()) %>% # analysis with dplyr!
box_write("delay_summary.xlsx") %>% # Convert to .xlsx, upload
box_add_description("Check out these averages!") # Add a description to your file!
Are how box.com identifies things. You can find them in an item's URL:
To use boxr, you need to enable API access for your box.com account. The process is slightly annoying. You only need to do it once - it takes around 2 minutes.
At https://www.box.com/developers/services, log in and create a new 'app' for your box.com account. You can call it anything you like. This won't do anything remotely like creating an app, but it does allow you to access your account via the API.
On the next screen, you'll want to set Content API Access Only, and http://localhost
as your redirect_uri as in the screenshot below.
This means passing your client_id and client_secret to the box_auth
function. These strings are not enough for someone to access your account maliciously. However, it's still a good idea to keep them safe, and out of any files or code which might be shared with others.
Run:
library(boxr)
box_auth()
And paste/type the client_id
and client_secret
when prompted. If these are valid, a browser window should open, for you to formally grant yourself access to your files at box.com.
If box_auth()
worked successfully, you won't need to do any of this again, and thanks to the magic of httr
everything should just work. Your client_id and client_secret will be securely stored in your R environment variables, your hashed OAuth2.0 token will stored at ~/.boxr-oauth
, .gitignore'd if necessary, and automatically refreshed when needed.
boxr is by default rather verbose, printing status to the console with cat
. This is 'rude' package behaviour, and may cause unwanted output if used in conjunction with the excellent knitr
package.
To supress messages produced using cat
, set boxr's verbose option with:
options(boxr.verbose = FALSE, boxr.progress = FALSE)
boxr aims to expedite data analysis/communication/distribution. Other ways to manipulate a box.com account include:
- The box desktop app
- The other boxr, written in Ruby. It's motivations are rather different, and it covers 100% of the box.com API (e.g account administration, etc.)
- box themselves provide a wide range of SDKs, including one for Python
If you don't like the idea of typing credentials into your console, you can put them straight into ~/.Renviron
yourself, prior to the R session:
BOX_CLIENT_ID="youridhere"
BOX_CLIENT_SECRET="yoursecrethere"
(Note the final blank line).
Always very welcome! If you'd like to submit a pull request for a new feature, ideally it would be documented, come with an addtion to NEWS.md, and have a test or two. This project has a standard Code of Conduct.
This proves tricky for the OAuth2.0 dance, as it relies on browser access. While not 'officially supported', it's possible to authenticate on a local machine to generate a cached token (by default, at ~/.boxr-oauth
), and then copy the file over to the eqivalent location on the remote machine. boxr can then read the copied file during remote code execution.
Via GitHub issues, please. It's been a while since I've read the R mailing lists!
If you run in to problems, first make sure that your credentials are correct, and that you're using the latest version of boxr. You can update boxr with:
install.packages("boxr")
Sometimes an old token can cause problems during authentication. If you're sure that your client_id
and client_secret
are correct, but box_auth()
isn't working, try the following in a fresh session:
install.packages("boxr") # Make sure you're using the latest version of boxr
library(boxr) # Load it
box_fresh_auth() # Delete the old token, and reauthenticate
This will delete the old token (by default stored at ~/.boxr-oauth
), and start the auth process afresh. A browser window will open, and you'll be prompted to sign in to your box account to verify yourself.
