Thanks again Jim. Sorry, again I'm enclosing incomplete not-runnable code. Modified like this it works with the new staxlab function which I inserted before the second staxlab call. How long before I don't need to insert it? I didn't see a way to select the specific axis, so I used top.line=5. Is that what I should do?
axis(1,tick=TRUE,at=horTicLocs,labels=rep("",length(horLabels)),padj=0) staxlab(1,at=horTicLocs,labels=horLabels,srt=90,adj=c(1,0)) nFrqTicInvls=9; frqTicLocs <- vector(length=nFrqTicInvls+1); frqLabels <- vector(length=nFrqTicInvls+1); frqInvl=(horAxisLims[2]-horAxisLims[1])/nFrqTicInvls for(i in 1:(nFrqTicInvls+1))frqTicLocs[i]=horAxisLims[1]+(i-1)*frqInvl for(i in 1:(nFrqTicInvls+1))frqLabels[i]=.jcall(OuWid,"S","sR",frqTicLocs[i],as.integer(4)) for(i in 1:(nFrqTicInvls+1))print(frqLabels[i]) axis(1,tick=TRUE,line=3.5,at=frqTicLocs,labels=rep("",length(frqLabels)),padj=0) staxlab(1,top.line=5,at=frqTicLocs,labels=frqLabels,srt=90) title(xlab="Cycles/Yr",line=6) Hurr -- View this message in context: http://r.789695.n4.nabble.com/Second-axis-on-bottom-of-graph-tp4690696p4690819.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.
