I want labels with superscripts in my legend. Furthermore, I want to construct the labels with paste function. I have figured out how to have a legend that uses my vector of values using paste. I have also used expression to get superscripts. But I can't use them together. Here are my attempts: A plot with the legend successfully plotting three legend items based on a vector of values but no superscript in legend. #set-up size=c(50, 100, 150) paste(size, "km^2", sep=" ") #output: paste function works # "50 km^2" "100 km^2" "150 km^2" #plot sample graph plot(x=c(1:10)*100, y=c(1:10)*10, col="red") points(x=c(8:17)*50, y=c(1:10)*7, col="green") points(x=c(8:17)*50, y=c(1:10)*12, col="blue") #legend legend(x = 'topleft', legend = paste(size, "km^2", sep=" "), col = c("red", "green", "blue"), pch=19,bty = 'n', xjust = 1, cex=0.8)And here I can print with superscripts on the graph but without paste. #print with superscript mtext(line=-4,adj=0,expression('km'^'2'*' size '))FAILED GRAPHS
