Appends to the body of a function an on.exit call to run at the end of the call.

Usage

register_onexit(
  f,
  ...,
  header_msg = NULL,
  use_device = FALSE,
  env = parent.frame(2),
  channel = Sys.getenv("SLACK_CHANNEL"),
  username = Sys.getenv("SLACK_USERNAME"),
  icon_emoji = Sys.getenv("SLACK_ICON_EMOJI"),
  token = Sys.getenv("SLACK_TOKEN")
)

Arguments

f: function or character.
...: expressions to be sent to Slack.
header_msg: boolean, message to append to start of Slack output, Default: NULL.
use_device: boolean, passes current image in the graphics device to Slack as part of f, Default: FALSE.
env: environment to assign appended function to with relation to the function environment, Default: parent.frame(2) (global environment).
channel: Channel, private group, or IM channel to send message to. Can be an encoded ID, or a name. See the chat.postMessage endpoint documentation for details.
username: what user should the bot be named as (chr).
icon_emoji: what emoji to use (chr) "" will mean use the default.
