You missed the part in "Writing R Extension" about .C() and .Call() arguments. You are mixing both approaches here, which usually ends badly.

Do some more reading, and maybe study some existing (simpler) examples / packages. You really do not need to engage OpenCV headers and libraries before you understand the basics better.
