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>
