[Rd] How to document man/*.Rd pages with images?

[Sean Robert McGuffee]

Hi,
I¹m trying to figure out how to put images into my package¹s help
documentation. I¹ve gotten to the point where I can put the images in the
/inst/doc/ directory. I have also gotten to the point where I have package
checks without any warnings. I couldn¹t find the terms ³picture,² ³image,²
or ³graphic² in a text search within the Writing R Extensions: 2 Writing R
documentation files
<http://cran.r-project.org/doc/manuals/R-exts.html#Writing-R-documentation-f
iles> 
I tried a couple of LaTeX guesses, but they lead to the following errors on
check:
Warning: /LAB/SRM/PROGS/R_PACKAGES/Ralign/man/Ralign139.Rd:3: unexpected
UNKNOWN '\usepackage'
Warning: /LAB/SRM/PROGS/R_PACKAGES/Ralign/man/Ralign139.Rd:36: unknown macro
'\includegraphics'
What is the right way to do this?
Thanks,
Sean
