OK, thanks to both of you for the clarifications. I guess part of my
confusion came from the numerous functions and concepts involved in
producing such labels:
- call vs string vs formula vs expression ...
- substitute, bquote, expression, "~", .(), ...

Thanks, I would never have expected this code to work, this is a mystery to
me! Actually, I thought xlab wanted an expression, but
bquote is used like this:
alpha <- 5
xlab <- bquote(.(alpha) / V * m^-3 * kg ^-2 * l^4)
plot(1, xlab = xlab)

seems to be happy with a formula. Also,
Try this:

DeaR list,
I'm a bit lost in the behavior of substitute and co.
I often use fairly long axis labels in my graphs (long to write, that
is). Typically, they would contain some greek letters and units with
exponents, as in:
xlab=expression(paste("text ", alpha, " / ", V,".", m^{-3}, ".",
kg
