Coloured output in the R console

Just a little fun today… the R console isn’t the most interesting of things… text is typically either black or red (assuming default settings in RStudio). There’s a package though called crayon which allows one to change the style of text in terms of colour, background and some font-type settings. It could be an interesting way to spice up summaries (I’m not recommending it, but it’s a possibility. As far as packages are concerned, it’s just another dependency…)…

devtools::install_github("r-lib/crayon")
library(crayon)
cat(green(
  'I am a green line ' %+%
  blue$underline$bold('with a blue substring') %+%
  yellow$italic(' that becomes yellow and italicised!\n')
))
