Try: x<-rnorm(20,0,5) y<-2*x+rnorm(20) # plot without condition plot(x,y) # some conditions on x and y index<- x<5 & y>3 plot(x[index],y[index]) Peter Wolf > >TIA > >Michael > > >_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/ > > _/ _/ _/_/_/ Hopkins Research Ltd > _/ _/ _/ _/ > _/_/_/_/ _/_/_/ http://www.hopkins-research.com/ > _/ _/ _/ _/ > _/ _/ _/ _/ 'touch the future' > >_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/ > >______________________________________________ >[email protected] mailing list >https://stat.ethz.ch/mailman/listinfo/r-help >PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html > > ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
