slackr - a package to send user messages & webhook API messages to Slack channels/users

The slackr package contains functions that make it possible to interact with the Slack messaging platform. When you need to share information/data from R, rather than resort to copy/paste in e-mails or other services like Skype, 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 (as R data files), and upload files.

Versions 1.4+ BREAK THINGS.

Support has been removed for the "old style" incoming web hooks (see "Setup" below for the required incoming web hook URL format).

The incoming webhook "token" is no longer required or used.

• Version 1.4.0.9000 new slackr_msg() + many fixes and BREAKING CHANGES (see above)

• Version 1.3.0.9000 Radically changed how slackr works. Functions have camelCase and under_score versions
• Version 1.2.3 added more parameter error cheking, remobved the need for ending ? on webhook URL and added defaults for missing setup parameters.
• Version 1.2.2 fixed issue (bug in 1.2.1 fix)

The following functions are implemented:

• slackr_setup : initialize necessary environment variables
• slackr : send stuff to Slack
• slackr_bot : send stuff to Slack using an incoming webhook URL
• dev_slackr : send the graphics contents of the current device to a to Slack channel
• ggslackr : send a ggplot object to a Slack channel (no existing device plot required, useful for scripts)
• save_slackr : save R objects to an RData file on Slack
• slackr_upload : upload any file to Slack
• slackr_users : get a data frame of Slack
• slackr_channels : get a data frame of Slack
• slackr_groups : get a data frame of Slack groups
• text_slackr : Send regular or preformatted messages to Slack
• slackr_msg : Slightly different version of text_slackr()

The slackr_setup() function will try to read setup values from a ~/.slackr (you can change the default) configuration file, which may be easier and more secure than passing them in manually (plus, will allow you to have multiple slackr configs for multiple Slack.com teams). The file is in Debian Control File (DCF) format since it really doesn't need to be JSON and R has a handy read.dcf() function since that's what DESCRIPTION files are coded in. Here's the basic format for the configuration file:

api_token: YOUR_FULL_API_TOKEN
channel: #general
username: slackr
incoming_webhook_url: https://hooks.slack.com/services/XXXXX/XXXXX/XXXXX

You can also change the default emoji icon (from the one you setup at integration creation time) with icon_emoji.
