Overview

About

Maintained by Matt KayeFirst published 2014-09-0813 releasesCRAN page ↗GitHub ↗

'Slack' https://slack.com/ provides a service for teams to collaborate by sharing messages, images, links, files and more. Functions are provided that make it possible to interact with the 'Slack' platform 'API'. When you need to share information or data from R, rather than resort to copy/ paste in e-mails or other services like 'Skype' https://www.skype.com/en/, you can use this package to send well-formatted output from multiple R objects and expressions to all teammates at the same time with little effort. You can also send images from the current graphics device, R objects, and upload files.
