Animation of an RStudio window where the generate function from emojiscape is being used to render to the console a 10 by 10 grid of emoji with a city theme, followed by an undergrowth scene with a smaller grid size, followed by the printing of a dataframe showing the set of emoji associated with the liminal scene, which are a large white square, a door and a lightbulb.

tl;dr

You can print a little emoji scene to your R console with the {emojiscape} package.

Really?

Regular readers will know that this blog is where I implement whimsical R daydreams. Today is no exception: I’ve made a tiny package to print a little randomised emoji scene to my console.

Why? I’ve seen people make cute emoji-based bots, which I’ve been interested in after making the @londonmapbot Twitter bot (post, source, BotWiki). I also enjoyed the fun of mild randomisation in my last post about #RecreationThursday.

I’ve made this completely for my own amusement, so no guarantees whatsoever.

Install

You can install {emojiscape} from GitHub.

## remotes::install_github("matt-dray/emojiscape")
library(emojiscape)

The package has one dependency: the GitHub-hosted {emo} package ¹ by Hadley Wickham. It implements emoji in R like emo::ji("sauropod") 🦕.

There’s no guarantee that these particular emoji will display correctly on your device and they may have different designs if you’re using another operating system.

Generate

Let’s generate() a scene.

The first one is nuts, lol: a classic deciduous woods.²

generate("woods")

## 🌳 🐿 🌰 🌰 🌳 🐿 🌰 🌳 🐿 🌰 
## 🌳 🐿 🌳 🌳 🌰 🌳 🌳 🌰 🌰 🌳

## 🌳 🌳 🐿 🌳 🌳 🌳 🌳 🌳 🌰 🐿

Hold your breath, we’re going to space. You can resize the output, but space is basically infinite and my console is not.

generate(
  terrain = "space",
  grid_size = 7  # i.e. a 7x7 grid
)

Here’s a little raccoon city. Perhaps the residents are evil. (That is a gamer joke, gg.)

generate("city", 5)

I have a PhD in dead leaves, so I had to add undergrowth. Ant you glad I included it?

generate("undergrowth", 5)

## 🍂 🐜 🍂 🐜 🍂 
## 🐜 🍄 🍂 🍂 🍂 
## 🍂 🍂 🍂 🍂 🍂 
## 🍂 🍂 🐜 🍂 🐜

Here endeth the puns.

Terrains

So what are all the available terrain options?

paste(as.list(args(generate))$terrain)[-1]

##  [1] "arable"      "city"        "desert"      "forest"      "garden"     
##  [6] "liminal"     "mountains"   "ocean"       "pastoral"    "polar"      
## [11] "rainforest"  "sky"         "space"       "suburbs"     "traffic"    
## [16] "undergrowth" "woods"

This list may go out of date if more options are added in future.

Frequencies

Use get_set() to see each terrain’s emoji set and their ‘suggested frequency’ slot. In general, the most common emoji is the one that defines the background or vegetation and the rarer ones are creatures or whatever.

get_set("mountains")

##     terrain                 name emoji     freq
## 1 mountains             mountain     ⛰   common
## 2 mountains snow_capped_mountain     🏔️ uncommon
## 3 mountains                 goat    🐐     rare

But you can totally mess with these emoji sampling probabilities in generate().

Any The Mountain Goats fans?

generate(
  terrain = "mountains",
  prob_common = 0.1,
  prob_uncommon = 0.2,
  prob_rare = 0.7  # INCREASE GOAT FREQUENCY
)

## 🐐 🏔️ 🐐 ⛰ 🐐 🐐 🐐 🏔️ 🐐 🐐 
## 🏔️ 🐐 ⛰ 🐐 🐐 🐐 🐐 🏔️ 🐐 🐐 
## 🐐 🐐 🏔️ 🐐 🐐 🐐 ⛰ 🐐 🐐 🐐 
## 🐐 🐐 🐐 🐐 ⛰ 🐐 🐐 🏔️ 🐐 🐐 
## 🐐 🐐 🐐 🐐 🏔️ 🐐 🐐 🐐 ⛰ 🐐 
## 🐐 🐐 🐐 🐐 🏔️ 🐐 🏔️ 🐐 🐐 🐐 
## 🏔️ 🐐 ⛰ 🏔️ 🐐 🐐 ⛰ 🐐 ⛰ 🐐 
## 🐐 🐐 🐐 ⛰ 🐐 ⛰ 🐐 🏔️ 🐐 🏔️ 
## 🏔️ 🐐 🐐 🐐 🐐 🐐 🏔️ 🏔️ 🏔️ 🏔️ 
## 🏔️ 🏔️ ⛰ 🐐 🐐 🏔️ 🐐 🐐 🏔️ 🐐

Approach

The generate() function is pretty simple. What it does is:

Creates a vector of emojis with a length of grid_size() squared, sampled from the specified terrain set with frequencies from the prob_* arguments
Coerces this vector to a matrix of length and width grid_size() (i.e. a square)
Loops over each row of the matrix with cat() to print the output to the console

It works.

Expansion

If you really want, you can add a terrain option by raising a new issue or pull request in the {emojiscape} GitHub repo. These are specified in the .get_emoji() function in the /R/utils.R script.
