Possibly easier: plot(x, y, log = "x") Cheers, Michael

Hello, The following is the general idea. x <-c(0.25,0.5,1,2,4,8,16,32) y <-c(1,1,1,1,0.9,0.8,0.6,0.2) plot(log(x),y,type="b", xaxt = "n") axis(1, at = log(x), labels = x) If the x values are not so "neat", you can adjust the axis ticks and labels using round/seq.

dear All I am trying to plot the following with the x axis on the log scale, but I would like the original x values to show up as labels: x <-c(0.25,0.5,1,2,4,8,16,32) y <-c(1,1,1,1,0.9,0.8,0.6,0.2) plot(log(x),y,type="b") here I would like the labels 0.25,0.5,1,2,4,8,16, and 32 to show on the plot at their respective "log scale" location apreciate the help, Andras [[alternative HTML version deleted]]
