Colleagues,
I am encountering difficulty adding formatted text to a graphic. Specifically,
I want to add a superscript in the middle of a text string but I would like to
format the text string on the fly. The commands:
plot(1,1)
ARG <- bquote('TEXT'^'\u00ae')
mtext(ARG, line=-2, side=1)
yield the desired output.
However, my goal is to paste together a string, then pass it to mtext. For
example:
plot(1,1)
PART1 <- 'TEXT'
PART2 <- '^'
PART3 <- '\u00ae'
ARG <- paste(PART1, PART2, PART3)
mtext(bquote(.(ARG)), line=-2, side=1) ## bquote(ARG) also
does not work
This does not work -- the unprocessed string:
TEXT ^ ®
is printed.
Obviously, I don't understand some aspect of passing arguments to bquote. Of
note, I tried "expression" instead of bquote but I was not able to get the
registered sign ('\u00ae') to appear as a superscript.
Any help would be appreciated.
