cowsay makes it easy to print messages, warnings, or character strings with various animals and other creatures.
Stable version from CRAN
install.packages("cowsay")or dev version from GitHub
install.packages("devtools")
devtools::install_github("sckott/cowsay")library(cowsay)The animals, and other ascii creatures, are all in a single named character vector that is exported from the package. Thus, you can access each animal yourself, and do whatever you want with it.
As of this writing, there are 44 animals.
The names of the animals:
sort(names(animals))
#> [1] "ant" "anxiouscat" "bat" "bat2" "behindcat"
#> [6] "bigcat" "buffalo" "cat" "chicken" "chuck"
#> [11] "clippy" "cow" "daemon" "duck" "duckling"
#> [16] "egret" "endlesshorse" "facecat" "fish" "frog"
#> [21] "ghost" "grumpycat" "hypnotoad" "longcat" "longtailcat"
#> [26] "monkey" "mushroom" "owl" "pig" "poop"
#> [31] "pumpkin" "rabbit" "shark" "shortcat" "signbunny"
#> [36] "smallcat" "snowman" "spider" "squirrel" "squirrel2"
#> [41] "stretchycat" "trilobite" "turkey" "yoda"For example, access the cow

library(multicolor)We rely on the crayon package for color and the multicolor package for multiple colors. The arguments you supply to what_color and by_color can be strings – either the color name or a hex value – or a function of class crayon.
say(what = "fortune",
by = "rabbit",
what_color = "#FF4500",
by_color = "red")
#> Colors cannot be applied in this environment :( Try using a terminal or RStudio.

#> colors() are all supported as are any rgb values that evaluate to a string. Supplying multiple colors for what_color or by_color is allowed, as long as they’re in a character vector. “rainbow” is also allowed.
