Is there a way to output text to the R console in color

问题

I am writing a script and I want to output text messages to the console with different colors depending on conditions. For example: RED for errors and BLUE for warnings, etc.

I am using RStudio.

回答1:

Check out the new crayon package:

library(crayon)
cat(blue("Hello", "world!\n"))

More info on the GitHub page.

Works in RStudio 1.2.360+

The xterm256 package by Romain Francoise allows this sort of thing in general on any console that understands xterm256 interrupts.
