Dear all,
In my R plot, I would like to add the title as "Estimator vs. Eta",
where I want to use the greek letter eta.
I was trying to use expression(plain("Estimator vs.") *eta* ). It
does not
seem to work.
Can anyone familiar with this give some help?
Thank you very much.

You wouldn't be able to say a <- plain("Estimator vs.") * eta * either (not even if plain was an actual numeric function and eta a numeric variable). -- Peter Dalgaard, Professor, Center for Statistics, Copenhagen Business School Solbjerg Plads 3, 2000 Frederiksberg, Denmark Phone: (+45)38153501 Email: pd.mes at cbs.dk Priv: PDalgd at gmail.com
Hi,
Try this:
plot(0,0)
?title(expression(paste(plain("Estimator vs. "),eta,sep="
")))

Dear all,
? In my R plot, I would like to add the title as "Estimator vs. Eta",
where I want to use the greek letter eta.
I was trying to use expression(plain("Estimator? vs.") *eta* ). It
does not
seem to work.
Can anyone familiar with this give some help?
