Dear Helpers,
I would like to make plots with titles for different data sets and
different parameters. So a useful title should combine data name
and parameter for clarity. The following is a simplified code example with
two plots. The first title doesn't show sigma as a math symbol, while the
second one doesn't contain the s value as a numeric value - I could
manually change the s value, but when there are many different s values,
this is not a good solution. Thanks!
s <- 1
y <- rnorm(100)
plot(y, main=paste("data", "sigma=", s))
plot(y, main=expression(paste("data", sigma,"=", s)))

Dear John, read ?plotmath, it is good, I
was not aware of its existence; then
backquote s like so:
plot(y, main=bquote(paste(
"data" ~~ widehat(aleph)
%notin% .(s)^.(s))))

Thanks to Dunkan, Rasmus and Bert. Will keep the very useful tips. Best!

Good; for me copying the sigma unicode
character into that line works too:
plot(y, main=paste("data?=", s))
How curious

"Plotmath seems to be the right way to do it. " Not sure I agree with that. Paul Murrell put together plotmath around 2000 prior to the widescale development and adoption of the unicode standard (corrections/modifications welcome!). So at the time, there really was no other way to handle this for most OS'es. With UTF8 now being generally supported for Unicode, plotmath constructions may not be needed for simple symbol labeling, as here. Of course for more complex symbolism (fractions, integrals, ...) it will be. ?plotmath talks about this and has links to further issues and options, btw. In other words, unicode may indeed be better than my suggestion of plotmath here. I would welcome comments from others who are more knowledgeable about this than I am. Bert

I think that comment is fair *on graphics devices that can handle unicode*. So that is true for Cairo-based graphics devices, but not for the pdf() or postscript() devices, for example. Paul

Eventhough I'm a heavy user of pdf(), I
didn't notice at first that the sigma
gets converted to two dots with the
error messages
Warning messages:
1: In title(...) :
conversion failure on 'data ?= 1' in 'mbcsToSbcs': dot substituted for <cf>
2: In title(...) :
conversion failure on 'data ?= 1' in 'mbcsToSbcs': dot substituted for <83>
3: In title(...) :
conversion failure on 'data ?= 1' in 'mbcsToSbcs': dot substituted for <cf>
4: In title(...) :
conversion failure on 'data ?= 1' in 'mbcsToSbcs': dot substituted for <83>
like if it was a Han character (most
likely three dots in that case), I just
ran with cpolwart's suggestion in
whatever is the default on the R
console, probably that Cairo thing.
png() works ofc.
