Your text is a vector of length 2 and you are plotting each element over the same x,y coordinates, hence the overlap. You could either add a second x-coordinate to spread things out: text( c(0.5,0.55), 0.5, c( expression( eta ), paste( ' = ', val ) ) ) or use bquote: text( 0.5, 0.5, bquote(eta == .(val) ) ) Hope that helps ______________________________________________ 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.
