I'm trying to use multiple plotting colors in my code. My first "ifelse" statement successfully does what I want. However, now I want anything less than -4.5 to be green and the rest black. I want another "col" argument but can only use one. How could I go about getting separate colors for anything above 4.5 ?and less than -4.5? plot(three, type="h", col=ifelse(three > 4.5, "red", "black"), xlim=c(0,500), ylim=range(three), lwd=2, ? ? xlab="Chromosome", ylab="Z-Score", font.lab=2, font=2, main="Upregulated Genes in Patient Sample")
How about: my.colors <- ifelse(three > 4.5, "red", "black") my.colors[three < -4.5] <- 'green' plot(three, type='h', col=my.colors, ...)
