[R] Converting from encapsulated postscript to encapsulated pdf

[Frank E Harrell Jr]

I have several old encapsulated postscript graphics generated by R that 
I want to include in a LaTeX Beamer presentation so I want them in pdf. 
  Under Ubuntu linux typing

convert z.eps z.pdf (to use ImageMagick)

results in a nice looking graphic but the bounding box is lost.  Doing

convert z.eps z.epdf

results in a fuzzy image with a good bounding box.

Does anyone have a nice solution?

Thanks
Frank
