[R] Using R2HTML

[Prof. Brian Ripley]

HTMLplot is documented to

     Exports the active graphic to a JPEG or GIF file and add it to a
     target HTML output, by writing the <IMG> tag.

but the code uses dev.print which is intended to *printing* from a screen
device.  Please send report to the author of R2HTML: he probably should be
using dev.copy.

I presume you are doing this in a script and so your current device is
a postscript device.
