A client asked me to develop a method to post a recurring message to a particular Slack channel. The slackr package easily enables inbound webhook Slack channel message posting in just a few lines of R.
library(slackr) setwd("C:/slackproject/") slackr_setup(config_file="slackr.dcf") text_slackr('Any text message you wish to push to the Slack channel goes here.', as_user=FALSE)
This is the configuration information file referenced in that script:
api_token: <your slack API token> channel: <name-of-slack-channel> icon_emoji: :<emoji name>: username: <you can insert any name here - doesn't have to be a 'real' slack account>
