[R] help on plot on the log scale but showing original values on axis
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]]

[R] help on plot on the log scale but showing original values on axis
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.

Possibly easier: plot(x, y, log = "x") Cheers, Michael On Aug 30, 2012, at 5:47 AM, Rui Barradas <ruipbarradas at sapo.pt> wrote:> 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. > > Hope this helps, > > Rui Barradas > > Em 30-08-2012 11:12, Andras Farkas escreveu: >> 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]] >> >> >> >> ______________________________________________ >> R-help at r-project.org mailing list >> https://stat.ethz.ch/mailman/listinfo/r-help >> PLEASE do read the posting guide http://www.R-project.org/posting-guide.html >> and provide commented, minimal, self-contained, reproducible code. > > > [[alternative HTML version deleted]] > > ______________________________________________ > R-help at r-project.org mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code.
