How to define desired numbers to a vector based on the present numbers
HI, May be this also works: plot(x,col=as.numeric(factor(x))) A.K. ----- Original Message ----- From: Rui Barradas <ruipbarradas at sapo.pt> To: Suparna Mitra <suparna.mitra.sm at gmail.com> Cc: r-help at r-project.org Sent: Friday, June 21, 2013 11:32 AM Subject: Re: [R] How to define desired numbers to a vector based on the present numbers Hello, I'm not sure I understand. You want to attribute a color number 1:7 to each element of your vector? Maybe the following will do. x <- scan(text = " 43 43 43 43? 0 39 13 39 50 39 39 23 23 32? 0 13 32 23 32 23? 0 13 13? 0 ") cols <- rep(1:7, rle(x[order(x)])$lengths)[order(order(x))] plot(x, col = cols) Hope this helps, Rui Barradas Em 21-06-2013 16:13, Suparna Mitra escreveu:
Hello R experts, ? ? I want to? define desired numbers to a vector based on the present numbers. Can anybody please help me? Obviously I found worst ways to do it, but I believe there must be any better way. I have vector as
X
? [1] 43 43 43 43? 0 39 13 39 50 39 39 23 23 32? 0 13 32 23 32 23? 0 13 13? 0 Now I want to colour a plot with unic cols based on this vector. I want to baseplot. But now the problem in normal col pallet these nos has repetition. Thus I tried to ? library(RColorBrewer)
coll<-colorRampPalette(brewer.pal(9, "Set1"))(50)
and then use this vector as col. But there also the colours are not enough bright. So I am trying to set new a vector reading this present vector. Obviously I can type out manually as coll=c(rep(1,4),0,2 .... But rather I am trying for some automation with which function or similar But still now I am struggling with this. Can anybody please help me. Basic thing is some way to reads the vector and define a new col vector from 1:7 Thanks a lot, Mitra ??? [[alternative HTML version deleted]]
