Hi everyone. I'm trying to display the r^2 of a linear regression on a plot using text(...). I first build the string to display. However, I can't find why this is not working (it display literally r^2 instead of r superscript 2). r2string = expression(paste(r^2)," = ", r2); Any help would be greatly appreciated, Phil -- View this message in context: http://r.789695.n4.nabble.com/Mathematical-expression-tp2299253p2299253.html Sent from the R help mailing list archive at Nabble.com.
