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.
1) If you are getting errors then you should post them.
2) There is no `sep =` argument in plotmath's paste function.
3) It is an error to put double quotes before the `expression`
function call.
4) once those errors are corrected the "±" is properly rendered in the
title.
