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


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

plot(expression(alpha<1))

enter image description here

plot(expression(alpha<<1))

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

Solution

  • Using unicode

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