Another question: is it possible to keep the superscripts unbolded?
For example if you run the codes below, it can be seen that using
the expression(bold(paste(...))) command will result in the text
being bolded but not the superscripts.
ourtitle <- function(title, footnotes=NULL) {
if (length(footnotes) > 0) {
fn <- paste(footnotes, collapse=' ')
title <- eval(substitute(expression(bold(paste(title, ""^fn))),
try instead:
expression(bold(paste(title^plain(fn))
list(title=title, fn=fn)))
}
title
}
plot(0, type="n")
text(1,0, expression(bold(paste("stuff",""^1, " "^2, " "^3))))
text(1,0.5,ourtitle("stuff",1:3))

Sigh; that's because I forget to include it in the 'substitute' list.
Here is a version that works (and has been tested...).
ourtitle <- function(title, footnotes=NULL) {
if (length(footnotes) > 0) {
fn <- paste(footnotes, collapse=' ')
title <- eval(substitute(expression(bold(paste(title, ""^fn))),
list(title=title, fn=fn)))
}
title
}

I tried writing that function before, but the expression() command
is not preserved when we incorporate it into a function(). The
first example you gave me, if run in R, produced a title that reads
"title" instead of "stuff". It seems that in this case the
expression() can't read the character string in the argument
specified in the function() command.

You probably want to write your own titling function to add
superscripts. The following code will serve as a reasonable
starting point:
# make the title expression
ourtitle <- function(title, footnotes=NULL) {
if (length(footnotes) > 0) {
fn <- paste(footnotes, collapse=' ')
title <- eval(substitute(expression(bold(paste(title, ""^fn))),
list(fn=fn)))
}
title
}
# example with footnotes
tt <- ourtitle("stuff", 1:3)
plot(1, 1)
title(tt)
# example without footnotes
plot(1, 1)
title(ourtitle("stuff"))
Note that the only way I could make this work was to combine the
footnote list before calling the eval-substitute-expression code; I
cannot get it to work by applying things ot a list.

Dear R users,
I recently developed a plotting function in R and introduced it to
my coworkers. The function is designed to make plotting easier and
more efficient, which will in turn be more cost-effective for the
company. The reviews for the function have been positive thus far,
except for one issue -- addition of superscripts to the title. We
need superscipts in the titles sometimes to highlight footnotes
which appear at the bottom of the plots.
The syntax for supersciprts, however, is rather cumbersome,
especially in titles since it needs to be bolded. So far the only
way of superscripting is to use the expression() function. But to
go about formatting the text such that it appears bolded as a
title in my plots, I would have to type in the command
text(expression(bold(paste("text for title",""^1)))....)
In some cases, the plot would require 3 footnotes to be shown, and
the code would be
text(expression(bold(paste("text for title",""^1, " "^2, "
"^3))).....)
Most of my coworkers are still in the process of picking up R,
some have never used R before. The above commands may be a little
too much for them to handle.
Is there an easier way of superscripting texts in R? It would be
great if any of you know of alternative ways other than using the
expression() function.
I greatly appreciate your help.
Thank you.
Sincerely,
Shang
