Dear HelpeRs,
I would like to do sg similar to:
plot(c(0,100), c(0,100), xaxs="i", yaxs="i", type="n")
txt <- paste("a =", a, "%\n b =", b, " km2", sep="")
text(95, 95, txt, adj=c(1,1))
just with the "km2" formatted with 2 in a superscript.
I thought
txt <- substitute("a = "*a*" %\n b ="*b*" km"*phantom()^2, list(a=a,b=b))
would do it. However it does not work.
Is it possible to formulate "multi-line" expressions in plotmath? What
is the trick?
Or I should break txt into separate lines, and place the lines
independently using text and strheight()?
Thanks,
Bálint
