How to write much less than symbol (<<) in plotmath in R?

Question

I'm trying to write the << symbol in R but I'm not succeeding. Any tips?

plot(expression(alpha<1))

plot(expression(alpha<<1))

Error: unexpected input in "plot(expression(alpha<<"

Answer 1

Using unicode

plot(1, 1, xlab = bquote(alpha~"\u226A"~1))

Answer 2

This is the closest I am so far, how does this work for you?

plot(
        x = 1:10,
        y = 1:10,
        main = expression(paste(alpha, "<<", 1))
)
