Use sub-/superscript and special characters in legend texts of R plots

Question

I generate a plot for multiple datasets. Each of the datasets should get it\'s own legend, which might contain greek letters, plotmath symbols or sub and superscrition. I\'d lik

Answer 1

Try this:

 legend_texts = expression(
   Omega^2, Omega*10)

 legend(
   "topleft"
   , legend = legend_texts
   , col = c(1:2)
   , pch = c(1:2)
   , lty = 1
   )

I could not tell if you wanted Omega^10 or Omega*10 or Omega%*%10 , but they all would produce acceptable plotmath expressions.
