HI,
Try this:
plot(1:10, type='n')
?newtxt<-bquote(paste("Temperature", "(",degree*C,")",sep=""))
?mtext(newtxt,3)

Subject: [R] How to join two plotmath type expressions
If I have two variables set, one of which holds an expression, for example:
label <- 'Temperature'
unit <- expression(paste(degree,'C'))
how can I join them together for use in mtext (or equivalent)? The
following is conceptually what I want to do, but will obviously not work:
plot(0:1)
mtext(paste(label,unit))
Preferably, I would like this to work if one, both or neither of label
and unit are expressions.
Thanks,
Trevor.
