David,
I tried your suggestion, still not working:
x<-3
plot(1:10)
title(bquote(bold(x) <= bold(as.character(.(x)) )))
It prints x<=as.character(3) as title
Kids these days! No innovative spirit. Why in my day... they would be
jumping with the obvious fix to an elder's error.
x<-3
plot(1:10)
title( bquote(bold(x) <= bold(.(as.character(x)) )))

David.
Thanks
John

Thank you David and Bert.
x<-3plot(1:10)
title(bquote( x <= .(x) ))
would do what I want. But I also want the title printed in bold
font. so I
tried
x<-3
plot(1:10)
title(bquote(bold(x <= .(x)) ))
But this did not print the "less than equal to" symbol and the
number 3 (from
variable x) in bold. Anyway to solve that?
Nope. The Symbol font has no bold type face. Bolding of numbers
_can_ be done
inside bquote with bold(as.character(.(x)) )

Thanks again!

Hi, how can I print "<=" (I mean the symbol of just one
character) in the
main
title of a plot?
for example:
plot(1:10, main=paste("x<=", x))
where variable x is some number generated on the fly.
x <- 2.718
plot(0, 0)
title(bquote( x %<=% .(x) ))
I think John wants the mathematical symbol. As was pointed out in a
question
last week, the `<=` plotmath symbol needs to be flanked by operands.
Non-printing operands can be created with the phantom function:
title(main=expression(phantom("")<=phantom("")) )
Contrary to Gunters's comment, this is probably going to work on
all the three
major OS platforms. It depends only on whether there is a Symbol
font mapped
to
the output device.
?plotmath
Yes. The details are there.
