R生成随机的十六进制颜色

Question

How can I generate a random hex color with R? I want to create a function that will spit out strings in this format:

# "255 0 0"
# "245 32 456"
# ...

Would I need to create a function that uses the sample function three times? or is there a simpler way to accomplish this in R? Thank you.

Answer 1

How about

paste(sample(0:255,size=3,replace=TRUE),collapse=" ")

?
