How to get the colour name from colour code in R?

R ProgrammingServer Side ProgrammingProgramming

To get the color name from color code, we can use the color_id function of plotrix package. If we have a vector of colour codes say x then the colour name can be found by using the command sapply(x,color.id).

Example

> x<-c("#FF0000","#FF1F00","#FF3D00","#FF5C00","#FF7A00","#FF9900","#FFB800","#FFD600","#FFF500","#EBFF00","#CCFF00","#ADFF00","#8FFF00","#70FF00","#52FF00","#33FF00","#14FF00","#00FF0A","#00FF29","#00FF47","#00FF66","#00FF85","#00FFA3","#00FFC2","#00FFE0","#00FFFF","#00E0FF","#00C2FF","#00A3FF","#0085FF","#0066FF","#0047FF","#0029FF","#000AFF","#1400FF","#3300FF","#5200FF","#7000FF","#8F00FF","#AD00FF","#CC00FF","#EB00FF","#FF00F5","#FF00D6","#FF00B8","#FF0099","#FF007A","#FF005C","#FF003D","#FF001F")
> x
