In tmooney101/slacktest003: Send Messages, Images, R Objects and Files to 'Slack' Channels/Users

Description

Takes an expr, evaluates it and sends the output to a Slack chat destination. Useful for logging, messaging on long compute tasks or general information sharing.

Usage

slackr_msg(txt = "", channel = Sys.getenv("SLACK_CHANNEL"),
  username = Sys.getenv("SLACK_USERNAME"),
  icon_emoji = Sys.getenv("SLACK_ICON_EMOJI"),
  api_token = Sys.getenv("SLACK_API_TOKEN"), ...)

slackrMsg(txt = "", channel = Sys.getenv("SLACK_CHANNEL"),
  username = Sys.getenv("SLACK_USERNAME"),
  icon_emoji = Sys.getenv("SLACK_ICON_EMOJI"),
  api_token = Sys.getenv("SLACK_API_TOKEN"), ...)

Arguments

txt	text message to send to Slack. If a character vector of length > 1 is passed in, they will be combined and separated by newlines.
channel	which channel to post the message to (chr)
username	what user should the bot be named as (chr)
icon_emoji	what emoji to use (chr) "" will mean use the default
api_token	your full slack.com API token
...	other arguments passed to the Slack API chat.postMessage call

Details

By default, everyting but expr will be looked for in a "SLACK_" environment variable. You can override or just specify these values directly instead, but it's probably better to call slackrSetup first.

Note

You need a https://www.slack.com account and will also need to setup an API token https://api.slack.com/ Also, you can pass in add_user=TRUE as part of the ... parameters and the Slack API will post the message as your logged-in user account (this will override anything set in username)
