Mostly no.  I don't suppose the Hershey script font is close enough?  e.g.,

plot.new()
text(.5, .5, "F", vfont=c("script", "plain"))

On some devices, it is possible to set a custom font family (e.g., you 
may be able to produce a postscript file with a Type 1 version of the 
mathcal font), but this is only per-file if at all (e.g., it would make 
all text in the file mathcal).  An exception is the windows device -- 
extra fonts can be set up (see the file $RHOME/etc/devga) and accessed 
via the "font" parameter.  e.g.,

plot(1:20, type="n")
text(1:20, 1:20, "F", font=1:20)

In this case, if you can get a True Type version of the mathcal font, 
and set it up properly, then you should be able to do just the text you 
want.

Greater flexibility in the specification of fonts is in the pipeline, 
but is at least an R version away.
