You need two steps. in your plot() set yaxt="n" so that R doesn't draw any y axis. Then, after plotting, you draw a custom y axis with axis() x <- seq.int(0,1,0.2) y <- x plot(x,y, yaxt="n") axis(2,at=c(0.2,0.6,1)) m. > > I have tried ylim=c(0:1) that did not work, and I tried yrange > > Thanks > > > > Silje > > > > ?`?.??.???`?.??.???`?.? ><(((?> > > Silje-Kristin Jensen > > Norsk Polarinstitutt / Norwegian Polar Insitute > Polarmilj?senteret > N-9296 Troms? > Phone: +47 95166782 > E-mail: [EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> > > JaP please don't print this e-mail unless you really need to > > > > [[alternative HTML version deleted]] > > ______________________________________________ > 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. -- Marianne Promberger Graduate student in Psychology http://www.psych.upenn.edu/~mpromber ______________________________________________ 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.
