Working from the example in FAQ 7.15 suggests something like
dist=" is the xth power of R"
plot(rnorm(10),main=substitute(R^x*dist,list(dist=dist)))
which works fine. A slightly more compact version is
plot(rnorm(10),main=bquote(R^x*.(dist)))
If that output isn't what you want you will need to explain what you want
more precisely.
