Look at help("plotmath").
> plot(1:10, xlab=bquote(Log(sqrt("Total area") * (mm)))) # small space before (mm)
> plot(1:10, xlab=bquote(Log(sqrt("Total area") ~ (mm)))) # more space before (mm)
For your next question:
> # now use .(var) to interpolate value of variable 'var' into a plot label.
> varName <- "Mean Acceleration" # render as uninterpreted text
> units <- bquote(m/s^2) # render in math notation
> plot(1:10, xlab=bquote(Log(sqrt(.(varName)) ~ (.(units)))))
