Re: [R] Plot colors
You could do something like this: mydata=c(1,2,1,1,6,7,-1,-1,5,-1) color= as.numeric(mydata== -1) +1 plot(mydata,col=color) This will give you a plot where the -1's are in red (color = 2) and the other numbers in black (color=1).

Try: x - c(1,2,1,1,6,7,-1,-1,5,-1) plot(x, col = ifelse(x == -1, red, black), pch = 16) On Thu, May 29, 2008 at 1:23 PM, uv [EMAIL PROTECTED] wrote: Hi.
