I'm trying to format text on a plot such that the string is vertical but the letters are horizonal. I tried text(1,1,label="output", srt=270) This gives the string rotation I want, but that rotates the entire "output" so the letters are also rotated. I've also tried text(1,1,label="output", srt=270, crt=270) to no avail. par()$crt doesn't seem to affect
