[R] Plotmath with values?

[Sarah Goslee]

Hi all,

I hadn't used bquote before, so I gave this a try, only to encounter some odd
behavior.

R 2.8.0 on Fedora Core 8 (no RPM for 2.8.1 yet)
"vanilla" session with no packages loaded (same behavior with my usual
set of packages).

R --vanilla

aa <- 22
x11()
plot(1, main=paste("a == ", aa)) # plot with title
plot(, main = bquote(a == .(aa))) # plot _without_ title
plot(1, main=paste("a == ", aa)) # plot _without_ title - ???

plot(1, main="abc") # plot _without_ title - ???
dev.off()

# after trying bquote(), no plots have titles until I close
# the device and open a new one.

x11()
plot(1, main="abc") # plot with title
dev.off()

The png device does not have a plot with a title. postscript() works as
expected.

What am I missing?

Thanks,
Sarah
