In seecolor: View Colors Used in R Objects in the Console

knitr::opts_chunk$set(
  collapse = TRUE,
  comment = "#>"
)

suppressMessages({
  library(seecolor)

1. Use the cursor to select object to print in the console.

# Highlight objects by cursor to show the contained colors
pick_color()

# Change output styles, "ribbon" or "mosaic"
pick_color(type = "r")

# Change the length of the color blocks
pick_color(blank.len = 1)

2. Use print_color to print color literals, palettes and ggplot2 objects.

Note: the colors may appear not distingushable in the html version, but they always work fine in console.

print_color(c("red", "navy", "pink", "#E58700", "limegreen"))
print_color(c("red", "navy", "pink", "#E58700", "limegreen"), 
            type = "r")

print_color(palette(rainbow(6)), blank.len = 1)
print_color(palette(rainbow(6)), type = 'r')

p1 <- ggplot(mpg) +
  geom_point(aes(displ, cyl, color = manufacturer))
print_color(p1)
print_color(p1, type = 'r')

3. Use open_sample() to open a sample file to have an instant try.

# Open the pre-defined test file
open_sample()
