This zooming function on the R-Wiki page was very neat: http://wiki.r-project.org/rwiki/doku.php?id=tips:graphics-misc:interactive_zooming
Also, to answer question (a), maybe these examples might help? ## add elements to plot plot(1:10,1:10) lines(1:10,(1:10)/2) points(1:10,(1:10)/1.5) ## add second y-axis par(mar=c(5,4,2,4)+0.1) plot(1:10,1:10) par(new=TRUE) plot(-20:20,20:-20,col=4, type="l",axes=FALSE, xlab="",ylab="", xaxs="i", xlim=par("usr")[1:2]) axis(4,col=4,col.axis=4) mtext("second y-axis label",4,outer=TRUE,padj=-2,col=4) --- Jim Lemon <[EMAIL PROTECTED]> wrote: > El-ad David Amir wrote: > > I'm slowly moving my statistical analysis from Matlab to R, and find > myself > > missing two features: > > > > a) How do I mimic Matlab's 'hold on'?
