You did not give it to plot command? You can modify it by calling plot with axes=FALSE and put labels from row names by axis command. plot(m[,5],type="o", axes=FALSE) axis(1, at=1:3,labels=row.names(m)) Regards Petr > > How can I solve this problem?? > > -- > View this message in context: http://r.789695.n4.nabble.com/Plot-a-matrix- > tp3065094p3065163.html > Sent from the R help mailing list archive at Nabble.com. > > ______________________________________________ > 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. ______________________________________________ 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.
