well, figured it out, apparently placing the bquote results in a
vector doesn't result in a vector of expressions, so you have to
coerce it like so:
dev.new()
plot.new()
plot.window(xlim = c(0, 1), ylim = c(0, 1))
legend("topleft", legend = bquote(paste("foo bar ", R^2 == .(2^2))),
fill = "red")

well, if You wish, You can always write scripts in R and then send it to

You can do that, as well as install RKWard if you want a "gui" front end
