My recollection is that it is impacted upon by your setting of the
height and width arguments.
I have used the seminar package for creating slides with embedded EPS
files from R. Using the standard U.S. "letter" size paper, I have:
postscript(..., width = 9.5, height = 7.5, ...)
This leaves 1 inch margins on the right and left sides of the page and
half inch margins on the top and bottom.
I don't recall the specifics, but if I went much larger than the above
settings, the landscape page would get rotated to portrait.
In the LaTeX code, I then have:
\begin{slide}
\begin{center}
\includegraphics[width=0.9\textwidth]{FileName.eps}
\end{center}
\end{slide}
The above seems to work in the seminar package and I believe that
prosper is built upon the former. Note the 'width' setting.
You will likely need to make comparable adjustments using the 'a4' page
size in order to maintain a landscape orientation.
