Hello This is a problem I encountered repeatedly and I found no answer that made me really happy. I hope it is not too trivial. I would like to give the concentration of a substance in a plot title: 5 ug/ml substance the '5' would be a variable and the ug should be micrograms (with greek letter mu). It is the mu that causes the problems for me. I failed using various combinations of paste, expression and bquote. I would be very grateful if someone could help me (or point me to the solution, which I might have overlooked).
Like this? plot(0,0) conc <- 5 title(main=bquote(.(conc)*" "*mu*g/ml*" substance"))
