This is a followup to a recent post on using atop() to obtain multiline expressions.
My reading of the plotmath docs makes it clear that issuing (in base graphics) the specification par(cex = 2) doubles symbols and regular text in subsequent plotmath expressions. However, it is unclear to me what specifying cex _within_ the annotation function using plotmath should do, and the following seems to want to have it both ways: ignore/obey )or maybe recycle?) plot(1,type="n", xaxt='n', yaxt='n', ann=FALSE) text(1,1,labels=expression(atop(sigma,"some text")),cex = 2) ## obeys the cex specification in symbols and text HOWEVER plot(1,type="n", xaxt='n', yaxt='n', ann=FALSE) text(1,1,labels=expression(atop(atop(sigma,"some text"),"another level")),cex = 2) ## ??? For even more fun, try: plot(1,type="n", xaxt='n', yaxt='n', ann=FALSE) text(1,1,labels=expression(atop(atop(sigma,"some text"),"another level")),cex = 1:2) ##???? So I confess to being flummoxed. Enlightenment would be much appreciated.
