I am trying to plot text combined with an object value and a

obv = 5
text = "Population mean ="
ss = ^o # degrees
Something like this (very naive so you get the idea):
expression(text, obv, ss)
paste(text, obv) # works ...but of course I either lose the value of
obv or
the superscript in the translation using expression, and bquote
doesn't seem
to accept the asterisk before the first element.
I had trouble figuring out your real intent, since you have only been
describing what didn't work but see if this his halfway there:
plot(1,1)
obv = 5
text = "Population mean =" # you should really avoid using function
names for variables!
text(.8,.8, bquote(.(text)~.(obv)^o) )
The ^o seems a bit of a dodge but it looks ok so if you're happy, go
Instead of ^o, use the word 'degree' (see ?plotmath)
text(.8,.8, bquote(.(text)~.(obv)*degree) )
and, personally, I would let R handle the '=' sign:
txt <- "Pop mean"
text(1, 1.1, bquote(.(txt) == .(obv)*degree))
Peter Ehlers
with it.
I am a little bungled by the varying syntax used for bquote and all
the
rest; sometimes R seems more complicated than it needs to be for a
relatively simple problem (and for me this is one of those cases!)...
