colorout

The package "colorout" in CRAN is to colorize R output on terminal emulators. It considerably improves visibility in R interactive operations.

Although R usually works on ESS for me, to run R on a terminal emulator sometimes saves time when prompt or short trail or reading helps.

My color palette

Since the default color palette is dissatisfied, I made a new color setting with setOutputColors256().

>   library("colorout")
>   setOutputColors256(normal = 252, number = 222, string = 203,
+                      const = 120, stderror = c(3, 0, 244),
+                      warn = c(1, 0, 1), error = c(1, 15), verbose = FALSE)

The result.

Settings as autorun

For always using it in gnome-terminal, the following was added into $HOME/.Rprofile to be run whenever starting R.

if(Sys.getenv("COLORTERM") != ""){
  library("colorout")
  setOutputColors256(normal = 252, number = 222, string = 203,
                     const = 120, stderror = c(3, 0, 244),
                     warn = c(1, 0, 1), error = c(1, 15), verbose = FALSE)
}

The environmental variable "COLORTERM" is set as "gnome-terminal" when I use gnome-terminal.
