How to literally print superscripts in R not used in labels or legends?

I know that in a graph one can use expression() to include superscripts, e.g.

plot(rnorm(20), xlab = expression(paste("n"^"th")))

However, I literally want to print out superscripts, so I can store them in rtf files later. In fact, I want to use them to indicate the degree of statistical significance associated with my regression coefficients (you know, like "0.24^*").

With "expression(paste("n"^"th"))", I tried print(), cat(), eval(), and get() but none of them worked.

I am currently using the "rtf" package to output ".doc" files. If someone suggests using other ways/packages, it is OK if R itself cannot display rich formats in the console, but the results can be stored in some files anyway.

As you've seen, the ?plotmath expressions only work within plots. Nothing in R is optimized for rtf output.

But reading the RTF vignette, it's clear you can write rtf commands in your output and there is a command for superscripting. Try

library(rtf)

rtf<-RTF("text.doc")
addText(rtf,"Hello\n")
addText(rtf,"0.05{\\super*}\n")
addText(rtf,"0.15*\n")
addText(rtf,"End")
done(rtf)

plot(rnorm(20), xlab = as.character("n^*"))

or even

plot(rnorm(20), xlab = paste0("n","^","th"))

Not sure why you want to use expression()
