slackr_bot: Send result of R expressions to a Slack channel via webhook API

Description

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

Usage

slackr_bot(
  ...,
  channel = "",
  username = "",
  icon_emoji = "",
  incoming_webhook_url = Sys.getenv("SLACK_INCOMING_URL_PREFIX")
)

Arguments

...

incoming_webhook_url

which slack.com API endpoint URL to use (see section Webhook URLs for details)

Webhook URLs

Webhook URLs look like:

• https://hooks.slack.com/services/XXXXX/XXXXX/XXXXX

OLD STYLE WEBHOOKS ARE NO LONGER SUPPORTED

Details

By default, everything 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 slackr_setup() first.
