ggslackr: Post a ggplot to a Slack channel

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

Description

Unlike the dev_slackr function, this one takes a ggplot object, eliminating the need to have a graphics device (think use in scripts).

Usage

ggslackr(plot = last_plot(), channels = Sys.getenv("SLACK_CHANNEL"),
  scale = 1, width = par("din")[1], height = par("din")[2],
  units = c("in", "cm", "mm"), dpi = 300, limitsize = TRUE,
  api_token = Sys.getenv("SLACK_API_TOKEN"), file = "ggplot", ...)

Arguments

plot	ggplot object to save, defaults to last plot displayed
channels	list of channels to post image to
scale	scaling factor
width	width (defaults to the width of current plotting window)
height	height (defaults to the height of current plotting window)
units	units for width and height when either one is explicitly specified (in, cm, or mm)
dpi	dpi to use for raster graphics
limitsize	when TRUE (the default), ggsave will not save images larger than 50x50 inches, to prevent the common error of specifying dimensions in pixels.
api_token	the slack.com full API token (chr)
file	prefix for filenames (defaults to ggplot)
...	other arguments passed to graphics device

Value

httr response object (invisibly)

Note

You need to setup a full API token (i.e. not a webhook & not OAuth) for this to work Also, uou 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)

Examples

## Not run: 
slackr_setup()
ggslackr(qplot(mpg, wt, data=mtcars))

## End(Not run)
