hi,i am trying to label a plot axis with the equivalent of the latex $n_*$. i initially tried expression(paste(italic(n)["*"])) but this made the * absolutely tiny and centred about midway wrt the n. then expression(paste(italic(n)[textstyle("*")])) made the * about the right size but now it looks more like a superscript than a subscript. does anyone have an idea of how to get the * to the "right" subscript position (ie. somewhere near the baseline of the n)? thanks!
I think these *are* correct: remember that an asterisk is a superscript. However, what you see depends on the graphics device and font you used, and you have not told us (pace the posting guide). If your OS and device support Unicode, try \u2217:
expression(paste(italic(n)["\u2217"])) looks about right to me (X11() on Linux).
