这篇文章主要介绍R语言中colors()的颜色有哪些,文中介绍的非常详细,具有一定的参考价值,感兴趣的小伙伴们一定要看完!
R进行绘图多会涉及颜色搭配问题,利用colors()可以获得R种的657种颜色名称。
head(colors(),20) [1] "white" "aliceblue" "antiquewhite" "antiquewhite1" [5] "antiquewhite2" "…

head(colors(),20) [1] "white" "aliceblue" "antiquewhite" "antiquewhite1" [5] "antiquewhite2" "antiquewhite3" "antiquewhite4" "aquamarine" [9] "aquamarine1" "aquamarine2" "aquamarine3" "aquamarine4" [13] "azure" "azure1" "azure2" "azure3" [17] "azure4" "beige" "bisque" "bisque1"
每个颜色名称具体对应的颜色,可以通过绘图呈现出来
pdf(file = "RColors.pdf",height = 20,width = 30) par(mar=c(0,0,0,0)) plot(0, 0, type = "n", xlim = c(0, 1), ylim = c(0, 1), axes = FALSE, xlab = "", ylab = "") line=30 col=22 rect( rep((0:(col - 1)/col),line) , sort(rep((0:(line - 1)/line),col),decreasing=T) , rep((1:col/col),line) , sort(rep((1:line/line),col),decreasing=T), border = "light gray" , col=colors()[seq(1,line*col)]) text( rep((0:(col - 1)/col),line)+0.02 , sort(rep((0:(line - 1)/line),col),decreasing=T)+0.015 , colors()[seq(1,line*col)] , cex=0.9) dev.off()
