You'll need to show us the source, but a guess based on "File ended 
while scanning use of \HeaderA." is that one of your titles or names 
contains characters that are confusing LaTeX.

You can also try

R CMD Rd2pdf --no-clean foo.Rd

to see what LaTeX got produced from the foo.Rd man page.  That will 
likely contain an error if the full manual does.
