R asks the X server to use the server-side specified font, but your X
server does not know that font.
Most applications these days use client-side fonts. That is, they have
freetype render the font locally and send a pixmap to the server for
each glyph. As such, most distributions no longer bother installing
server-side bitmap fonts by default.
The command xlsfonts will show what server-side fonts your X server
knows. In particular:
xlsfonts -fn -adobe-helvetica-*-*-*-*-*-*-*-*-*-*-*-*
will list all of the variations of adobe-helvetica your X server knows.
I'm not sure which fedora package you want. My dist calls them:
media-fonts/font-adobe-75dpi
media-fonts/font-adobe-100dpi
The bitmap fonts have neither a 16pt nor a 16pixel version. They do
have 17 pixel and 14 & 18 pt versions. And the server will scale to
match the request.
See:
http://stat.ethz.ch/R-manual/R-patched/library/grDevices/html/x11Fonts.html
for details on how to specify a server-side font which you *do* have
(use xlsfonts to see what those are).
Or you can switch to using cairo rather than xlib:

That will let you use the fonts with which you probably are more familiar.
