Muhammad, Here's one option: barplot(1:5,col=gray(seq(0,1,length=5))) Norm Olsen Fisheries and Oceans Canada -----Original Message----- From: r-help-bounces at stat.math.ethz.ch To: R-help at stat.math.ethz.ch Sent: 5/13/2005 11:40 AM Subject: [R] How to convert color to black & white Dear all, Could someone please explain to me how to convert color to black & white. For example: barplot(1:5,col = rainbow(5)) Because I need to print my plot to save my ink color printer. I don't want to convert to grayscale, but keep it as an RGB. I would be very happy if anyone could help me. Thank you very much in advance. Kindly regards, Muhammad Subianto
