Dear List,
I am trying to label a plot with the symbol +/- sigma. Using something like
- expression (2*sigma) gives me the symbol 2ó. However, adding +/- to it
beats me.
The code I am using is: plot(x,y,type="l",main=" expression(paste("±",
plain(2*ó)),sep="").
Any suggestion will be appreciated.
Best
