Hi Tim, You might want to try it with the following:
par(usr=c(-2,1,ymin,ymax) Where -2 and 1 are the exponents for your x-values, and ymin and ymax the margins you want for your y-values. Then you plot as usual adding the following parameters: plot(x,y,....,log="x",xlim=c(10^par("usr")[1:2]),xaxp=c(0.01,10,1)) Hope this will work for you! It might also help to read through the help-files on "?par()" where all graphical parameters are explained. /Birte ______________________________________________ R-help@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.
